Takeshi Saji SG2 鑽石大馬士革 Sujihiki 270mm 鐵木

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.

The soft cladding enables the thinning process to be a lot easier than a honyaki or monosteel construction. And in the case where the cladding steel are stainless in nature, it can offer protection for the carbon or semi-stainless cores against rusting and discoluoring.

The etching process starts with the knife being thoroughly cleaned to remove any oils or residues. A protective mask may be applied to the areas not intended to be etched. The blade is then submerged in an acidic solution, such as ferric chloride, which reacts with the different layers of steel at varying rates. This creates a layer of dark oxide on the surface of the blade where the thickness of the oxide varies according to the reactiveness of the steel. After etching, the knife is neutralized in a baking soda solution, rinsed, and dried. The final step involves polishing the blade to highlight the etched design, enhancing both the knife's beauty and showcasing the craftsmanship of its maker.
