The Manufacturing Process for Utsumi U&U and Nova handmade shears
What is CNC (Computer Numerical Value Contorol) Technology?

CNC is shorthand for computer-numerically controlled machinery which 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 consistent rainbow-colored finish which results from the precision machining using CNC technology. The resulting deep radian hollow permits the implement to be repeatedly sharpened to a very fine edge during the entire life of the implement. The process is computer-controlled to produce shears of consistently high and even quality.

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