Next, the Honbazuke process involves the Katana edge being sharpened with an ancient 3-step process, which sharpens the blade twice on whetstones, followed by mirror polishing on a leather wheel. This process was used over 1000 years ago for samurai swords to create the ultimate sharpness. The Criodur process gives the steel hardness for blade retention, flexibility, and highly corrosion resistant. To deliver the outstanding performance, the blade is hand-honed at the traditional Japanese blade angle of 9 to 12 degrees; on each side, which results in a scalpel-like sharpness. This outstanding performing blade is complimented by a stunning durable D-shape Micarta handle, featuring a mosaic pin, red spacers, and a metal end-cap with logo that adds balance.
