Hatsukokoro's Saihyo(細氷, fine ice) is a line that I would consider as the "performance looker" these knives would have a stunning finish but not relying on it as the only selling point, the steel, the grind and the profile will still be performance oriented.

This Saihyo line is equipped with Suminagashi style stainless damascus cladding, finished with a mirror polish, it is a very densely packed, high contrast and defined damascus, which combines with the mirror polish would give the blade a dazzling look. The grind of these knives do not fall short behind, with the 210mm gyuto's spine thickness measures 1.9mm above the heel, the Saihyo line is a collection of lasers. Paired with the TAKEFU SG2 powder metallurgy steel, you could easily put on a wicked edge and expect it to hold very well.

If we consider the highly polished core steel as clear water and the dense damascus pattern as cluster of fine ice, the name would match perfectly with the imagery created by the blade. The entire blade is like the face of an arctic river, with fine ice flowing down from the spine to the edge can bring. That, is a very poetic scene that appears in front of my eyes when I pick up these knives.

Great artistic Thin behind the edge Excellent performance	High budget Mirror polish can be hard to maintain

Care Instruction

Don't cut hard things! Japanese knives are brittle so bone hacking is a NO NO!
Wash with neutral detergent after use, and wipe dry;
Please don't wash knife with dishwasher, it will damage the wood handle;
Be careful not to leave the knife close to a heat source for a long time;
It is a lot more dangerous to cut with a blunt knife than a sharp knife!
It is best to sharpen a Japanese knife regularly on a waterstone.

Profile: Santoku

The Santoku knife, embodying the meaning "three uses," is a cornerstone in Japanese kitchens, adept at slicing, dicing, and mincing. Esteemed for its versatility, it features a blade length typically between 15cm and 20cm (6 to 8 inches), catering to a wide array of culinary tasks. Distinguished by its less pointy tip compared to the Gyuto, the Santoku boasts a unique profile that contributes to its functionality and popularity. Its design is tailored to provide ease and efficiency in preparation, also because of its less aggressive prrofile, making it a preferred choice for home cooks.

Steel: SG2 / R2
SG2, also known as Super Gold 2 or R2 steel, is a high-end powdered tool steel by Takefu Special Steel, known for its excellent edge retention, wear resistance, and ability to achieve a hardness of up to 64 HRC. Identical to Kobelco Steel's R2, it's prized in premium knife making for its fine edge sharpness and durability. The powdered nature ensures uniform carbide distribution, enhancing toughness and reducing chipping risks. SG2/R2 is ideal for those seeking top performance and longevity in their cutting tools.

Construction: Sanmai - Stainless Damascus Clad

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.

Finish: Mirror Polish

Mirror Polish is a simplistic yet hightly demanding process, where the roughness of the metal surface is gradually removed with higher and higher grit abrasives, leading to a extremly smooth surface with only specular reflection, just like a mirror.
The Mirror Polish can be applied to various constructions, ranging from Damascus to Honyaki. It can reveal the beautiful Hamon on the Honyaki blade, and form textural contrast on damascus. The perfect surface is highly appreciated, but it also means a lot of care must be give to avoid it being scratched.
