Originated in 1946, Toshu Kitchen Knife Shop has served a number of professionals with their unique knife-making methods such as "hammered flame forging" and "Edo-Togi grinding". Although the brand is not widely known worldwide, the second generation master, Mr.Tozaki has inherited the rare technique of knife sharpening, which is highly sophisticated and elaborately applied on each piece of his work.
Most notably, all Toshu knives are 100% hand sharpened by Mr. Tozaki while the majority of knife makers rely on more economical processes. This hand sharpened edge line shows slight imperfection in terms of the appearance but bears unparalleled sharpness.
Hammered flame forging is one of Toshu knives' specialties, the traditional forging method used for Japanese sword manufacturing. This method is performed by heating the raw material in a 1,000℃ flame and welding/shaping all with manual hammering process.
Kurouchi（黒打）is a type of knives that are only polished the edge line and left with black residue appearing after forging and quenching. The black part of every Kurouchi looks different to each other and shows a little imperfection in their looks. However, this rustic design is aesthetically pleasing to eyes and feels traditional craftsmanship.
