This is a knife set from Tsuji Culinary Institute. I used it for about a year several years ago, but I bought a new set, so I'm selling this one since I have no use for it. I used it in the Japanese cuisine program. The knives are all steel, not stainless, so they are prone to rust. I sharpened them on a flat whetstone, so the sharpness and appearance are relatively good. They are not double-edged. The handles and sheaths are dirty. The deba knife has a scratch (last photo). I have lightly polished them. I lost the petty knife and the carving knife, and I bought my own after I enrolled, so they are not included. There are no name stickers. The case is made of synthetic leather, so it's a bit heavy. Tsuji Cho Knives Japanese knives
