This is a Château Laguiole sommelier knife. I am selling it to organize my collection, and will remove the listing at the end of February. This is an older model, but it still has the sticker and the body is in very good condition, so it may have some rarity! (In the older models, the ones made with natural materials like buffalo horn often have the sticker peeled off.) The button on the case is cracked, but it can be used without any problems.
