21C produces and supplies various industrial cutters such as Vertical Blade, Wheel Cutter, Trimming Blade, and Lens Cutter & Knife used in MLCC.
We hold patents for blade manufacturing and have Cutter’s Edge calibration technology using Femto-second Laser, implementing the sharpest and longest-lived Edge.
It manages the flawless edge without chipping of Cutting Edge through automated inspection equipment, and manages it at the highest level in terms of illumination and integrity of cutting part.
