Instructions for Use of Hard Alloy Tungsten Steel Seal Cutting Knife:

1. It is only suitable to engrave stone seals (such as Qingtian, Shoushan, Bahrain, Liaoning Frozen Stone, etc.) on organic glass and other printing materials. Do not use them on hard materials such as jade, porcelain, crystal, pebbles, marble, and bluestone.

2. Do not use hammers or other tools to strike the tail during engraving to prevent breakage.

3. It should be prevented from falling onto hard surfaces such as cement and ceramic tiles to damage the cutting edge.

4. If the cutting edge becomes dull after being engraved for a long time, please polish it on a 1000 grit diamond grinding disc or the diamond small grinding plate we provided.
