This is an Asso sommelier knife that I purchased about 25 years ago for work. It's about two sizes larger than a Château Laguiole and easier to use, so I used it as my main knife instead of the Laguiole. I'm now using Kanetsune (Asso's overseas brand) and Asso's Damascus steel version, so I no longer have a need for this one, and that's why I'm putting it up for sale.
