This a rarity.
Brass pins in the handle, rosewood handle, (ROSEWOOD!!) carbon steel, not stainless, hand hammered in the early seventies by some old man in in the Sabatier Thiers Issard factory in France.
Carbon steel blade that is easy to sharpen unlike the Japanese knives that are in fashion now.
13 inch blade it's huge, yet due to it's construction it's very light. Tapered tang in the handle, that's done for balance and to reduce weight that cannot be done by hot drop forging only by a craftsman with hammer forging. You will notice the knife is not symmetrical in the forth photo you see the side that how a hand forge created the blade. 13 inches in length 10 is common, 12 a little less, so but 13in is just the right size for large amounts in a commercial kitchen and such an uncommon size!. The steel is softer than what is common now but that allows for easier sharpening and it responds to a steel in a few strokes unlike modern knives which are so hard they are difficult to sharpen and the modern hard knives chip easily.
It was on ebay and set me back 500 bucks
It's often in my hand for four hours a day.
