Togashi-San is the blacksmith behind this beautiful blade. One of the 25 certified traditional craftsmen in the region, he began forging blades since the age of 19, in 1967. The sharpener and polisher Yohei-San, also a certified traditional craftsman in the region, learned to sharpen the double-edged knife under the direction of one of the best sharpeners in the Sakai region.
Most Japanese knives are made like a ‘sandwich’, a very hard steel core covered on each side by softer steel. Hard steel is what makes a Japanese knife sharper and keeps its edge longer than other knives. Soft steel acts as a shock absorber to protect harder steel from damage. This is the common way to make a knife in Japan, but there is an older and more romantic way to make a knife, honyaki.
Less than 1% of knives in Japan are forged honyaki. Making a honyaki knife is like making a katana. The knife is made from a single piece of steel and thermally treated so that the edge is very hard and sharp for a very long time. The spine of the knife, although the same piece of steel, is softer and protects the blade from breaking.
