Yssingeaux 11 cm Classic Pocket Knife - Ironwood Handle

1 - In Stock

The Yssingeaux Collection represents the pinnacle of elegance within the 11 cm (4.33-inch) range. While it shares the storied lineage of the traditional Yssingeaux—evolving from 19th-century designs like the Issoire and Bourbonnais—this specific series is built to the exact high-luxury standards of our celebrated 5 Coqs collection. The primary distinction is the traditional slip joint mechanism, offering a smooth, non-locking operation for those who prefer a classic French feel.

Mirroring the 5 Coqs, every knife in this collection features a stunning Mother of Pearl inlay meticulously set into the "mouche" (the top of the spring). This shimmering detail provides a luminous contrast to the handle and highlights the master artisan's hand-chiseled filework. Handcrafted from start to finish by the Gilles® Fontenille Pataud workshop in Thiers, France, these knives utilize a hardened blade stop to ensure the edge never touches the internal spring, preserving its surgical sharpness.

Handle Character: This model features genuine Desert Ironwood (Olneya tesota) scales. One of the hardest and most stable woods on earth, Ironwood is prized for its rich, coffee-brown tones and shimmering grain. Its extreme density makes it exceptionally resistant to the elements, providing a rugged yet sophisticated handle that complements the luxury pearl inlay. The knife pictured is the exact one you will receive.

To guarantee you are satisfied with the unique character of the natural handle materials and the iridescent pearl detail, every knife in this collection is individually photographed. The specific masterpiece you select is the exact one we will ship from our Jacksonville inventory. We also provide free same-day engraving on the blade, handled in-house at our local warehouse, to ensure your order is personalized and shipped without delay.

Authenticity & Warranty

100% Made in France: Handcrafted in Thiers by Fontenille Pataud.

Lifetime Warranty: Guaranteed against manufacturer defects.

U.S. Support: Warranty and repair coordination via Jacksonville, Florida.

Shopping for a unique pocket knife not only holds the promise of ownership but the excitement of finally beholding an item admired through a screen. However, all too often, what was envisioned and what is unboxed bear a startling, sometimes painful discrepancy.

You will receive the actual folding knife shown in the photos.
No one wants to view photos of a beautiful and unique knife and receive something not even close to the representative image; this is why we take pictures of each piece. Select your One-Of-A-Kind knife!

Things to Look For
The file work on the springs (top of handle) are individually hand filled by a French artisan, therefore all are different. Additionally, two handles made from the same material can have very different patterns.

You need to know

  1. If you do not checkout after adding this unique folding knife to your cart, someone else may purchase it.
  2. After purchasing this knife the unique photo(s) may be replaced within hours. Feel free to save the actual photos of your knife for personal use.

Desert Ironwood (Olneya tesota) - One of the world hardest wood and most difficult to work with due to its density.

This increasingly rare wood comes from dead trees that have been left to dry in the desert heat for decades. As it starts to fossilize, the wood turns reddish brown with a golden hue and beautiful veining. The wood from this very slow growing tree can be well over 100 years old. Harvested in Arizona or Northwestern Mexico.

Good to know: Ironwood can sometimes show tiny knots or small depressions within the wood. This is not considered a defect but rather a characteristic of this wood.

Pocket knives are shipped same business day from Florida when ordered by 4 PM Eastern time. UPS delivery can be expected in 1 to 3 business days depending on destination. International shipping options are available at checkout.

Pocket Knife

Pocket Knives are designed for cutting only. Please do not use it as a screwdriver, crowbar, or wood chisel, as this can cause irreversible damage and void the warranty.

Corkscrews

Important Note on Use: Waiter-style corkscrews are designed for use with a secure grip on the bottle neck. Please do not use the tool by clamping the bottle between your knees and pulling the handle. This technique often applies excessive force, which is likely to bend the screw (worm) and will immediately void the product warranty.

To keep your pocket knife or corkscrew in top condition, follow these maintenance tips:

  1. Lubricate Moving Parts: Periodically apply a few drops of lubricant to all moving parts. This ensures smooth operation and extends the life of your knife.
  2. Hand Wash Only: Always hand-wash your pocket knife. After washing, dry it quickly with a soft towel to prevent rust and corrosion.
  3. Recommended Lubricant: We highly recommend using Sentry-Solutions Tuf Glide for all our folding knives. It provides excellent lubrication and protection.

Important Note: Tuf Glide is not considered a "food-safe" product. Avoid using it on knives that come into contact with food.

By following these simple steps, you can ensure that your item remains reliable and ready for your next adventure.
