Is the blade stone washed or mirrored?

The basic principle of mirror machining is the repeated polishing process of tool from rough grinding to fine grinding. The advanced mirror treatment effect makes the tool surface eye-catching, just like a mirror. The principle of stone washing method is that the blade is placed in sand grinding, and after continuous vibration and rotation, it is irregularly polished in all directions, forming various scratches or tiny pits. The treatment effect of the stone cleaning machine has the feeling of being old and retro. However, compared with mirror method, stone washing method will do great harm to tools if it is not chosen properly.
