The manufacturing process for Utsumi U&U and Nova handmade shears

What is CNC Technology?


CNC (Computer-Numerically Controlled) machinery allows for very fine tolerances in grinding of shears.  Utsumi utilizes CNC technology for grinding of both front and back hollow ground blades of its shears to achieve precision tolerances not otherwise attainable.


The grinding process which utilizes water to provide constant cooling, is designed so that the heat forged metal maintains its optimized characteristics.  Upon close examination one will notice the constant rainbow-colored finish which results from the precision machine using CNC technology.  The resulting deep radian hollow permits the implement to be repeatedly sharpened to ver find edge during the entire life of the implement.  The process is computer-controlled to produce shears of constantly high and even quality.


Once the computer-controlled machining process is complete, the final finish is performed by hand by skilled craftsman using time honored methods.  Utsumi’s skilled craftsmen sharpen, assemble, and find tune our products to meet the exact standards designed to guarantee years of use.
