Blade shape
For years we have made knives with the "KATAKIRIBA" and "HONZUKURI" blade shapes, which are based on the traditional Japanese sword. As a result, we applied the function of the time-honored Japanese sword to the knife, producing a knife which cuts well and has a strong blade design. With the KATAKIRIBA, the one side of the blade su**ce is convex and the opposing su**ce is a plane, while both sides of the HONZUKURI blade are the convex. These cutting edge shapes function wonderfully. However, production is time-consuming so the process is quite expensive. Upon further researching of the blade, we ascertained that the angle in a small area in the tip of the blade influences sharpness. So we developed a special grinding jig device, giving birth to the SINOGIZUKURI, where both sides of the blade are planes. (SHINOGI being the ridge between the blade and blade edge.) For this manufacturing process we developed a new, advanced technology. As a result of this, we realized the best edge angle near the haft of the blade is 30 degrees and in the point of the blade 24 degrees.(We adjusted the angle to 30 degrees in the haft side because power was most concentrated there, which improved toughness, and 24 degrees at the tip of the blade, where power was low. The angle changes continuously.) We were able to realize a blade that suits the human anatomy by this technology, resulting in its wide popularity.
大概意思是根据实验数据等,这个开锋角度对于锋利度和保持性最好呵呵~~~ |
