Sanmai(Three-Piece) is a common construction for double bevel knives where two pieces of softer cladding steel are forgewelded to each side of a harder core steel. The harder but more brittle core steel will form the hard cutting edge after heat treating, and the softer cladding will support the core to increase the overall strength of the blade.

Damascus Sanmai utilize damascus steel as the cladding material for the Sanmai construction, which adds aesthetic feature to the blade. On the Kitchen knives with stainless core steel, the damascus cladding will be stainless, this means they will also protect the carbon/semi-stainless core from rusting/discolouration.

The soft cladding enables the thinning process to be a lot easier than a honyaki or monosteel construction. However, when the cladding is made of damascus, whether etched, polished or mirror polished, the thinning process will take a toll on the cladding, meaning the damascus won't look the same as when it was taken out of the box.

The "Tsuchime" finish in Japanese kitchen knives refers to a distinctive hammered texture on the blade's surface. This traditional technique not only adds a unique aesthetic appeal but also provides practical benefits, such as reducing drag and preventing food from sticking to the blade during slicing. It's a hallmark of craftsmanship that blends functionality with artistry, making each knife not only a tool but a piece of art.
