    The Hatsukokoro Sunaarashi(砂嵐, Sandstorm) VG10 Kurozome line is the brand's pitch at high end home kitchen market. The dense damascus pattern, Kurozome dyed steel and mirror polish, these features all add cost to the knife but aren't oriented towards performance. However, the knife you get is stunning to say the least. The dyed black steel is mixed into a storm of undyed silver, two contrasting tone then both reflect light with their hight glossiness. This combination is so dazzling especially when the knife is rotated under the light, it do makes you feel like you are lost in a sandstorm when inspecting this Sunaarashi line up close.

    The beautiful apperance of this line doesn't hamper it from delivering great performance. With the spine of 210mm Gyuto measures at just below 2mm above the heel, these knives definitely falls under the "Laser" category. Such thin profile leads to a very thin cutting edge, and reduces resistance when cutting into thicker foods. There is one thing to be notice however, that is the mirror polish finish on this line is very smooth, it tend to creat drag/stickness when the blade is making a large area of contact with food, so if the cut is done in a slower motion, you could feel some friction as the blade is entering food like potato.

    Overall the Sunaarashi line is packed with aesthetic features, as well as sharpness. Although its price is on the higher side for a VG10 core knife, when compared to some competitors like the high-end VG10 made by Mcusta Zanmai or Miyabi, these knives can be seen as an alternative option that give lightness, sharpness and a different look.

    4. Be careful not to leave the knife close to a heat source for a long time;

    • Steel: VG10

      Takefu VG10, is a high-end stainless steel celebrated for its exceptional edge retention and sharpness. It is a popular choice among Japanese kitchen knife makers and widely used in various types of knives, including kitchen knives, folders, and fixed blades.

      VG10 achieves a hardness of around 60-61 HRC, with some makers pushing it to 62 HRC, ensuring good edge holding and stain resistance. The steel's composition includes 15% chromium (Cr) for corrosion resistance, 1% molybdenum (Mo), and 1.5% cobalt (Co) for matrix strengthening, leading to high hardness and durability. The addition of vanadium (V) refines its microstructure and, along with Cr and Mo, produces hard carbides that enhance wear resistance. VG10 is easy to sharpen, has good machinability, and supports secondary hardening with high-temperature tempering, making it suitable for blades that may undergo surface coating treatments up to about 450℃. Its well-rounded attributes make VG10 steel highly versatile, performing excellently in a range of applications from kitchen and general-purpose knives to machine blades.

    • 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.
