French Folding Knives, a.k.a., “Clasp Knives” in the Fur Trade

The French folding knife, a.k.a., “clasp knife” imported into the North American Fur Trade was one of the earliest known type of knife to be introduced to the New World – dating back to the 1600’s, possibly earlier. These blades have been recovered from French influenced sites throughout the territory of New France, which extended from Louisiana to Canada.

With the advent of the profitable North American fur trade, many French “coureur des bois” (independent French-Canadian traders) traded these knives with Native Americans in exchange for furs or simply as gifts, or “presents.” These folding knives are among the first types of knives imported into the French territory of the New World.

NOTE: The source for much of this material was an extremely large collection of writings, photographs, thoughts and documentation, from an unknown source. Clearly much of it was compiled by someone who spoke French. Much of the information I had to re-word, re-write, translate, or clarify. Whoever compiled much of this information clearly spent a long time doing so. And I hate to see it unavailable. So I’ve done my best to scan much of the documentation, OCR it to make it searchable. Some of it I’ve organized into this post, which will hopefully be ongoing in nature, as I find time to add to it.

Who used them? For what purpose?

Coureur des bois, Native Americans, Voyageurs (French Canadian fur trade transporters), New France inhabitants, soldiers, etc., all used French folding knives imported from the old country. They were a part of daily life, used both as tools and as tableware. Philippe Aubert de Gaspe in the “Anciens Canadiens,” published in 1863, stated that these knives were still being used in the first part of the 19th century Canada:

The habitants used, up until 50 years ago, their pocket knives during meals; the men, with “leaded” knives. A blacksmith would make the blade; the wooded handles would be decorated with pewter inlays, and because it wasn’t equipped with a spring, the user would have to constantly be holding down the blade with his thumb. The habitants would use these knives with great skill, but novices would often pinch their thumb in the process; some practice was necessary.

Coureur de bois

Frederic Remington spent quite a bit of time in Canada during his lifetime, and actually grew up in upstate New York, along the St. Lawrence River. He provided some good depictions of the inhabitants of New France.

According to Sidney Breeze (1814: 197-198), French inhabitants in the Illinois Country did not have what we would consider to be “table knives.” Contrast that with what we common find in the English settlements of Virginia, where table knives may be one of the most commonly found items on colonial era sites.

An assortment of English table knives found at the site of Byrnside’s Fort, ranging in date from the French and Indian War era through the Civil War era.

Frontier life was one of constant danger. “Each man and woman carried a large, dagger-like clasp knife for protection, usually dangling on a little chain fastened to the ceinture or belt. This knife doubled for table use. Peter Kalm (1716-1779), a Finnish clergyman and botanist who traveled to North America in 1748-51, kept a journal as he travelled throughout the wilds of French North America:

“The most popular custom here (in New-France), as a guest or at home, consists of placing on the table, beside the plate, spoon and fork; everyone must however use their own knife. As soon as they are seated, each person takes out their knife from their pants or skirt pockets.”

Another interesting tidbit, which possibly explains why some versions of the clasp knife have a rounded and blunted point:

“Cardinal Richelieu, then Prime Minister of France under Louis XIII, was entertaining one evening when a nobleman used a sharp knife to pick his teeth after a meal. Disgusted, Richelieu ordered the tips of all knives in inventory to be ground down.”

The Type 6 style blade of French folding knives (to be discussed below) is most likely the result of this description:

Characteristics of the French clasp knife found in French 17th and 18th century North America.

Here’s an example of a typical 18th century French folding knife, or “clasp knife,” the blade of which was dug near Fort Michilimackinac, Michigan and stamped (IEAN B. TIVET). This particular blade was given a contemporary horn handle using another folding knife found at Fort Louisbourg.

 Most of these knives have similarities and common traits with each other. Charles A. Hulse (Department of Anthropology, University of Michigan) gives some of the basic characteristics:

[A]ll have a horizontal transverse flange at the top of the butt of the blade and a hole through the blade at the base end. All of these blades originally had impressed upon them thenames of their makers (see “Known markings” in the table below) but in most cases pitting from rust has obliterated the manufacturer’s name for most of them. Although various forms of iron butcher knives were present in the Early and Middle French colonial periods they are not particularly useful in dating these temporal segments because they have notbeen carefully studied. Moreover, the French clasp-knife blade characteristic of these two periods is at present a better indicator of these early times. Butcher knives of the Middle French colonial period can be recognized because they have French Names stamped on the blade.”

Carl P. Russell gives some documentary evidence to work off of:

One of the early documentary evidences of their use in America  is  found in the records of the French Fox War expenses for the years 1715 and 1716 – “horn handled clasp knives, 6 livres a dozen.” Setzler and Jennings write of one fromthe Cherokee site, Peachtree Mound and Village, near Murphy, North Carolina. In the small museum at Tadoussac (now the Canadian Museum of Civilization), Quebec, is a specimen of French lineage in “fresh” condition, and Maxwell reports numerous disintegrated specimens recovered at Fort Michilimackinac, most of which are “indigenous to the earliest  French  features” (early 1700’s).  The French clasp knife almost always has a one-piece horn.”.

The early 18th century French painting below shows a “hawk bill” type blade on a folding knife. In this painting, the knife belongs to a set of accoutrements to cut and prepare tobacco  (tabac en carotte). This painting, along with others, indicates that this “hawk bill” type of clasp knife was used as a common utensil in everyday French life.

Below is a sketch of a french clasp knife featured in Buliard’s “AVICEPTOLOGIE FRANCAISE”, 1795, (Paris, Cussac, An III de la republique).

Very few examples of original French folding knives with original one-piece horn or wooden handles have survived into modern times. For the most part, our examples which can be tied to specific sites have been subjected to the ravages of burial in the ground. Therefore, we must look  back at the knife making methods used during 17th and 18th century France. 

Knife Construction

The knife industry in 18th century France was based on somewhat of an assembly line of specialists, all working together to complete the product. There was apparently a huge demand in Europe for folding knives. They were all the rage in the late 17th century, leading to the development of mass production in French factories. There were blacksmiths, sharpeners, quenchers, polishers, sleeve pressers and assemblers, all involved in the process. The sharpeners and polishers were brought together near water-powered mills in order to take advantage of their power. The other trades were generally installed in separate workshops.

The manufacture of Saint-Etienne’s jambettes, whose handle is generally comprised of sheep horn, requires the Martinist, who beats the iron to stretch it, the blacksmith, the fileer, the piercer, the grinder, the polisher, the tackler, the gunner, the bone sawyer, the whitener, who dries the horn handles and whitens the bone, the horn straightener, the assembler, the installer, the sharpener, the wiper, and finally the folder. That last job seems a little easy.

The below picture folding knife was excavated from the French fortress of Louisbourg:

Based on shape, construction and time period, knives such as these would be designated in France by the name “Eustache“. Most of the one-pin French folding (clasp knives) were called “jambettes or flatins” (because the handle looked like a leg, or jambe in French). Note the J.J Perret sketch of the “Jambette” or “Eustache” knives made in the famous St. Etiennes factory in France, below:

The print below demonstrates the different steps of common knife making of Fougeroux deBondaroy. The figures from 1 to 6 shows us the different steps in the making of a clasp-knife blade (lame a lentille d’arret en “tete de clou“) by blacksmiths. The figures 16 and 17 display the closed and open position of this type of knife. (Fougeroux de Bondaroy, L’art du coutelier, L’art du coutelier en ouvrages communs, vol. XVIII, 1772 ; Geneve : Slatkins Reprints, 1984, p.2)).

Here is an extraordinary example of an intact French clasp knife in museum grade condition: 9 1/2″ when open. Notice the brass washer and iron pin construction. The handle is woodand is pierced at the base possibly for a leather cord or chain. (… usually dangling on a little chain fastened to the belt. This knife doubled for table use.)

The below pictured knife has a handle which houses a Siamese French clasp knife blade. It has beveled edges ; the width narrows towards the blade top end, where it is upturned. The blade and handle are fastened by a single rivet. This handle and blade were found at the Fletcher Site Cemeteryin Bay County, Michigan. This site dates from 1745-1765.

Types of blades found in French North America, circa 1680-1760

Despite considerable variation, each of these knives can be classified in one of 4 categories: Siamois, Jambette dit Flatin, Capucin and a la Dauphine.

Engraving from the “Encyclopedie de Diderot et d’Alembert” – The “Art” of making knives using files.

According to Timothy J. Kent’s book “Ft Pontchartrain at Detroit, Volumes I & II, the Siamese knives were in fact the clasp knives shaped like those found on Laguiole knives today with a sharply pointed blades. There are numerous references of these in the Montreal merchants records of the very late 17th and earlyto mid 18th. Apparently, there were 2 types of Siamese knives: one with a rounded tip and one witha pointed tip. The only rounded tip clasp knives were the ones with up-turned and rounded blade tipas found on many sites such as Ft. Michilimackinac and Fort St.Joseph. 

Trade knives dug around the Ft. Michilimackinac area. Note the two at bottom right, being the “up-turned” knives, also known as “bowl knives” commonly found in that area.

The one characteristic that links the rounded and pointed tip is the somewhat upturn of the back of the blade preceeding a slight downturn towards the tip.

Couteaux Siamois et Flatin (Siamese or Flatin Knives)

The 1758 ledger entries of the Montreal outfitters Moniere and Brouillard concerning the provision of trade goods and supplies for trader Jean Chapron, it provides for Siamese knives:

1 gross of medium-size Siamese knives, round tip, 1 gross
of medium-size Siamese knives, pointed tip.

These would in fact be labelled Siamese types. Timothy J. Kent finds mentions of these as early as 1697 and they seem to replace the flatin or jambette knives from the merchant records at that point.

Thus the flatin or jambette type clasp knife mentionned so frequently in the 17th century must then have had blades shaped like the bill of a hawk. Both Flatin and Siamese knives exhibit a flattened knob which extends from the hinge end of the blade.

This is an original French “Flatin” blade found in Michigan. The handle was restored using horn. Marked IACQVES GIRARD:

Couteau Siamois

Type 1

Mary Elizabeth Good goes on to mention that:

[T]his type is characterized by a cutting edge which curves upward toward the tip, and a back edge which slopes downward toward the tip for about two-thirds of its length. This can be further identified in modern terminology as a “long clip point”, the type frequently found on present day pocket knives.

Type 2

Jambette dit Flatin

Those with blades shaped somewhat like the bill of a hawk are called Jambette did Flatin.

Type 1

Type 2

Type 3

Type 4

Type 5


Couteaux Capucin

As far as Capucin knives, Bondaroy describes their fabrication quite precisely :

The two-pin knife, which is also termed an a la capucine knife, is somewhat different from the one- pin sort. The blade is a little longer; and usually terminates, in a point. Otherwise, it is manufactured in the same manner; except for the butt of the blade.

As was explained earlier; the blade of the one-pin knife is held in a straight open position by a small knob or button on the butt of the tang, which rests against the handle. However; when this knife is folded, the knob protrudes, and sometimes hurts one’s hand or tears one’s pockets. Therefore, another model was designed, in order to eliminate the knob.

The top edge of the butt of the blade of the two-pin knife is notched, to form a type of tooth or extension [corner], which rests against the second pin to hold the blade open. This second pin is located slightly to the rear and a little higher than the one on which the blade pivots. The centre portion of the butt is rounded, so that it will not touch the second rivet while pivoting. The only difference between the two sorts of knives lies in the shape of the butt of the blade. In the case of a spring knife, the notch or extension stops against the head of the spring.

La Dauphine Knives

A la Dauphine knives are mentionned by Bondaroy and seem to differ from the Capucine, Eustache and Jambettes knife types.

Although knives are produced elsewhere in the Forez region, workshops in St. Etienne and in nearby Chambon manufacture annually 500 to 600,000 livres worth of jambettes, Eustache Dubois knives, dauphine knives, and a la capucine [folding] knives.

Knives with a dauphine, Montpelliel; or France-style blade, with one or two pins, with a moulded beech wood handle, 3 to 12 livres per gross

Knives with a Montpellier or dauphine-style blade, with a moulded handle of white sheep horn, 7 to 20 livres per gross

The only other type of knives found on French sites seem to be the ones that bear a knob which extends to the rear of the knife blade. Could they be the ones refered to as “a la Dauphine”?

This knob is actually a horizontal extension of the blade back. This knob could in essence serve the same purpose as does the raised knob on the Siamese or Flatin knives acting as a stop on the back of the handle. However, it is interesting to note that Bondaroy mentions that these could be manufactured with one (Flatin, Siamese) or two pins (Capuchin). Could it be that these types of blades could be mounted on both a one pin or two pin handle and are the ones refered to as “a la Dauphine”?

Maker’s Names and Markings on French Folding Knives

Since 1567, (Sentences des juges et consuls de la jurisdiction des marchands) all master knife makers in France are obliged to stamp a maker’s mark on their products. This mark, stamped on the blade, is the sign of quality on all of their products. It allows the “visitors”, chosen knife makers by their pars , to visit the workshops once a month, to identify the origin of the knives and for quality assurance purposes.

All deposited marks are hallmarked on a lead tablet that dates from the year 1591 until the French Revolution, which is conserved in a safe that is secured by five locks and entrusted to the keep of the oldest “Maitre-Coutelier” ; below is portion of the silver tablet for the years 1812-1857 for the town of Thiers, France.

The examination of these two tablets, which were handed down over hundreds of years, reveals thousands of various types of marks, including animals, organic matter, tools, numbers, alphabet letters, and so on:

It’s now believed that most markings found on French clasp knives traded into French North American sites are now recorded on the St. Etienne tablet in France.

Lead table with knife maker’s marks from Saint-Etienne (1737) (Musee de’ Saint-Etienne)
Close-up of the lead table with knife maker’s marks from Saint-Etienne (1737) (Musee de’ Saint-Etienne)

Almost all French clasp knife blades found on French sites are marked with a maker’s name or marks that are legible or partially so depending on the level of damage caused by oxidation. Some are too rusted and pitted to distinguish any markings. The maker’s name or mark always appears on one side of the blade (unlike trade axes), the side where the tip of the blade faces left. I have never seen any markings or maker’s name on the other side. This could be a knife making standard established in France at the time.

Fort Pontchartrain, a.k.a., Detroit, Michigan, circa 1701. Pleased with the strategic location and bank towering some thirty feet above the river, Cadillac landed and planted the flag of France in what is now Detroit, in the name of King Louis XIV. The erection of a fort began immediately. The stockade occupied about an acre of ground, made with 15 foot oak trees set three feet in the ground. Note that I’ve heard enclosing an acre of ground takes roughly 1,000 trees. Image from Detroit Historical Society.

In his book on fur trade life at Fort Pontchartrain, Timothy J. Kent provided great insight on the French clasp knives of the area:

In some instances, cutlers, names were recorded on cargo manifests, inventories of outfitters’ merchandise, and invoices of trade goods that were sent into the interior. For example, the 1733 cargo manifest of materiel which was shipped from the King’s warehouse at Rochefort, France to his store- houses in Canada listed 2,160 dog head knives from the shop of the cutler Perrin. (N.A.C., MG 1, C11A, Microfilm F-60,f. 109f.)

Products of this manufacturer were also listed among the merchandise of the Montreal outfitters Desauniers and De Brouage in May of 1741. Their stock included 636 small sheath knives with a horn grip made by Perrin, as well as 2,412 of these same knives in medium size by the cutlers Berte (Bertet) and Chapelon, plus 72 fine sheath knives by the cutler Bizaillon. In addition, the supply of Siamese folding knives which they had on hand included 48 large versions with a sharp-pointed blade from the shop of Bizaillon, plus 96 large examples with a handle of yellow boxwood from the cutler Jolivet. (Inventory of 9 au 23 Mai, 1741, Notary Boucault, A.N.Q.-M)

In 1742, an inventory of the merchandise belonging to a St. Lawrence-based trading firm also noted products by two of the above-named cutlers. The stock of horn- handled Siamese dog head knives of medium size which had been produced in the shop of Perrin included 144 examples with a pointed-tip blade and 738 others with a round-tip blade; in addition, Bizaillon’s work was represented by 102 fine sheath knives. (Kidd, untitled, p.128)

Products from the shop of the latter cutler were supplied on numerous occasions by the Montreal outfitter Moniere to interior traders. For instance, 72 of his sheath knives were sent to the Rainy Lake post in 1741,461 while 24 of these with a grip of yellow wood were provided to another trader the following year. (MMR, Bibliotheque Nationale du Quebec, Moonier, Brouillard, Blotter 1739-1751, p.456)

In 1758, Moniere included 24 Siamese folding knives by Bizaillon in another consignment of trade goods.

The fort was named “Pontchartrain du Detroit in honor of Count Jerome de Pontchartrain, Minister of Marine. The city name comes from the Detroit River. In French, “I’etroit du Lac Erie.” I think…..

The name PERRIN found on many of the Siamese blades refers to the family Perrin that were manufacturers of different metal implements and hardware in St.Etienne. In New-France, many records will mention PERRIN type knives referring to the maker and his particular style of knives. It is mentionned that a “couteaux Perrin” was a type of knife
where the handle was generally decorated with the head of a dog “tete de chien ; grands, petits ou moyens“. These were imported in vast quantities to New-France and kept in the King’s stores in Quebec city. : “37 grosses Couteaux flatins flamand Siamois et perrin a teste de chien” (National Archives of Canada of Canada from 1737). See Marcei Moussette, Des chateaux pour la traits des fourrures.

Understanding “Old French”

However, the names PALLE, TIVET, PERRIN are patronymes of blacksmiths, and more particularly makers and filers of door hinges that were found in the town of Saint-Etienne during the 17th and 18th century Their stamps are found on the 1737 lead table:

The location of Fort Pontchartrain was strategically situated to prevent the British from competing in the fur trade West of that point.

Many of these knives with maker’s name have symbols separating the names or placed between words. The diamond symbol a square a or a rectangle symbol was often placed between words (i.e. IEAN ♦ B TIVET). It is not uncommon to see certain words partially cut on the top line:

This was probably done to format the layout of the maker’s name (our modern version of justifying) and as well most likely for practical reasons when fabricating the stamp. Another interesting similarity amongst all blades is the fact that the maker’s name was stamped on one or two lines depending on the length of the name. Some would see this as a knife making standard in France at the time. There is usually the equivalent of number of letters on the top and bottom row of the maker’s name.

One thing that is quite interesting about the maker’s name is that most were written using “Old French,” which has many different variations in spelling. To put it simply, the concept that there was only one way to spell a word was one that was unknown to old French scribes or in this case knife makers. The existence of spelling variations in different regions — such as ‘mont‘ in Paris, ‘munt‘ in Normandy, for example is understandable. These are often the result of different pronunciations. Nevertheless, it is hard to accept the fact that even in texts written in a single regional dialect, by a single scribe, there are often different spellings of the same word, sometimes even within the same line! The reason for this is fairly simple: French had not yet standardized.

I’ll add that my brother Beau is a French professor at the University of Virginia, or training to be one – I’m not quite sure. He relates to me that the “French” spoken today is not quite the “French” spoken in the 18th Century. The language spoken in Paris was different than what was spoken in the rural areas. There were upwards of 43 different dialects around rural France – not to mention foreign colonies, such as New France in North America. He told me that it wasn’t until the 19th century that France started to centralize their language and education system. As such, reading and translating “Old French” can be quite complicated, as is discussed somewhat below.

Very important to remember that in old French the letter “V” can represent or be interpreted as a “U” or “V” (i.e. BVISSON = BUISSON or LEIEVNE = LEJEUNEand the same applies for the “I” which can be interpreted as a “J”, “r,”I” or “Y” (i.e. IEAN = JEAN). Another variance would be the “EZ” which would represent “E” (i.e. AYNEZ = AINE). As well, many times the letters would be missing either as a result of trying to condense many words on a small blade for practical reasons, or simply because of the fact that the French language was not standardized (i.e. FRANCOI = FRANCOIS).

The key to reading old French and deciphering words with variant spellings is to learn as many potential alternate spellings as possible. I have listed a few regular variations in spelling below:

The words “Layne” (L’aine = the elder), “Lefils” (le fils = the son or son of), “Per” (pere = the father), “Fil” (fils = son) was used on the markings due to the fact that knife making in France in the 17th, 18th and 19th centuries was a trade that was passed down from generation to generation.

Mary Elizabeth Good noted that:

[They are] characterized by a cutting edge which curves upward toward the tip, and a back edge which slopes downward toward the tip for about two-thirds of its length. This can be further identified in modern terminology as a “long clip point”, the type frequently found on present day pocket knives.

9 thoughts on “French Folding Knives, a.k.a., “Clasp Knives” in the Fur Trade

  1. Greatly enjoyed this post. I have loved the jambettes for several years and have struggled to locate information regarding tehm, Thank you for such a great informative article,

    • Believe it or not, that’s only about half done….. It’s still probably too big for one post as it is. I’m not sure if I’ll do a part 2, or add to this one.

  2. Thank you again. I will be waiting with great anticipation and excitement for the additional information.

  3. In the article you stated “Here’s an example of a typical 18th century French folding knife, or “clasp knife,” the blade of which was dug near Fort Michilimackinac, Michigan and stamped (IEAN B. TIVET). This particular blade was given a contemporary horn handle using another folding knife found at Fort Louisbourg.” Do you know what type of horns were used for the handle? Cow horns primarily are hollow and the tips portion with a core are not long enough for a handle or at least that has been my experience (yet to find one that could be used)?

    • Ok, I found this information: French knife makers would ordinarily use four types. Sheep horns for “Capucine” knives and folding knives. Ram horns for razors. Cow horns for pocket spring type knives, and antler for “serpent” handles and other various knives.

  4. Truly excellent and well researched publication. Thank you for all the effort you put into producing this

  5. John Bryan, I found this an awesome article. Thank you for this work.
    My question is on the St. Etienne tablet. Where can I find an online photo so that I can get an HD image and read the cartouches? I have a jambette that I would like to authenticate.
    Thank you
    John Ellis
