Hand-forged carbon steel handled in wenge with brass cutlers rivets. This was found  with a wax coating and a few small rust spiders. Blade has a small amount of wavyness to it and is a bit irregular along the spine but is otherwise straight on the overall balance. 

This ‘Plate-Semelle’ or ‘flat plate’ flat-forged knife was made in Thiers, France. it is a little difficult to say exactly when this was forged, Thirs Issard handled and blade marked with a laser a good amount of old stock blades starting in the 1990s to 2010s. This blade was either forged in the 80s to 90s and handled then with wenge and laser marked or is an older blade with a handle applied in the 90s to 2010s. 

These were the working-class knives of their day. These stout butcher's knives with a chef knife profile are similar to a Japanese yo-deba but would have been used by butchers as a light cleaver; stiff and strong, with a good toughness and an excellent sharpenability.

Plate-Semelle knives represent the last, large-scale commercial application of a very old forging technique. First, a bar of steel was drawn out to form the blade on an old martinet mechanical hammer. The tang (handle area) is next drawn out on the hammer, making for a tapered blade and tang, with a thick area where the two meet at the neck. When forging, a large bulge in the steel would remain, which would be hammered and ground to a small bulge.

The origins of the nearly ubiquitous bolster on western knives lie in this bulge of steel where the blade and tang meet. During the Middle Ages, fine cutlery offered at noble and church banquets was an important mark of wealth and power. In the making of fine cutlery, the bulge in the center of the knife was left thick and intricately ground, in addition to other embellishments to the knife. This feature became emblematic of fine cutlery. It lives on today in the more subdued, less ornate bolsters that characterize western culinary knives and still signify that a knife is of high quality.

This knife does not come sharpened. Please request sharpening in the order notes section of the cart page, if desired.

  • This is a reactive carbon steel knife.
  • Hand wash and towel dry after use. Do not air dry or place in the dishwasher.
  • Expect oxidation (color change, staining, spotting) with use.
  • Prolonged exposure to moisture or food debris will cause rust; remove any rust with a light abrasive.
  • Use only on a quality wooden cutting board.
  • Do not use on hard surfaces like bamboo or plates.
  • Don't twist or scrape the edge on the cutting surface to avoid early dulling and edge damage.

Medium - Western Carbon

We recommend hand sharpening on whetstones to a low-medium finish starting around 400 and progressing to around 1000 grit with a monodiachrome strop finish. Gentle use with steel honing rods work well for as-needed edge maintenance. Avoid pull-through sharpeners and non-water-cooled mechanized sharpening. If you have to use a honing rod to be able to use the knife comfortably, it's time to sharpen the knife.
