The Thomson blade is always renowned for its great cutting performance. Nagoya Hagata contributes to such quality cutting performance through its unique blade manufacturing method. We measure the blade movement using a high-speed camera to obtain the optimum bevel angle. Based on this a cross sectional drawing is prepared for design work. We then ask our partner blade manufacturer to fabricate. Our original blade, in which we use a more acute bevel angle in pursuit of a sharper edge and a straighter cut surface, promises unprecedented manufacturing accuracy.
