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.
"Edo" refers to the old name of Tokyo (150-400 years ago). "Edo-Togi grinding" is a traditional Japanese single-edged (Kataba) knife shaping technique applied to Western double-edged knives. In contrast to general double edged-knives with 50:50 blade bevel, "Edo-Togi" features 70:30, with one side nearly vertically ground and the other side ground to a clam shape (commonly known as Hamaguri-ba). This unique shape allows TOSHU knives to ensure exceptionally thin cutting edge and durability at the same time.
"Edo Togi grinding" requires meticulous technique with 0.1mm precision in shaping, all performed by master Mr. Tozaki by hands. There are few craftspersons left in Japan who can legitimately use this technique now.
