The history of knife manufacturing in Sakai of Osaka has been around for 600 years. The excellent “smithing” and “edging” techniques engender “sharpness”, the crystallization of both technologies. This the feature of Sakai blade with its long history. The feature of Japanese cuisine to enable the characteristics of the material is indebted to “sharp” knife, and Sakai knife is endorsed by many famous Japanese chefs. In addition, they produce scissors, used also for bonsai, with this same high technique. The feature of Sasuke’s scissors is “twist” like a propeller attached on the back of the blade. This structure for the blades of scissors is not flat but a subtle curve by handwork, which gives scissors an exquisite sharpness.
