While the cutting performance is fine when using a new cutter, the sharpness (finish) and life (blade retention) inevitably deteriorate after re-sharpening, leading the customer to give up and purchase new ones each time. They inquired whether re-sharpening could be an option to reduce costs. *For details on the solution and effects, please refer to the PDF document or feel free to contact us.
