Shiro Kamo Kurokumo SG2 Black Damascus Santoku 180mm Ebony

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 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.

This handle, crafted from a single piece of ebony, exemplifies minimalist elegance and functional design. Its unique octagonal shape, featuring a subtle taper, offers a comfortable grip and a visually appealing geometric profile. The ebony wood, known for its deep, rich color and durability, has been meticulously milled from a single block, ensuring a seamless construction that highlights the wood's natural beauty and grain. The handle's surface has been highly polished, achieving a glossy finish that not only enhances the ebony's luxurious dark hue but also provides a smooth, tactile experience for the user. This design choice reflects a minimalist approach, focusing on simplicity, quality, and usability. The combination of the octagonal shape with the taper adds a modern twist to the classic material, making it a standout piece that blends traditional craftsmanship with contemporary aesthetics.
