摘要

The insulating material cutting device comprises a cutting blade (1), where one side of the edge of the cutting blade is sharpened. Cutting micro-teeth (1.1) are formed at the cutting edge, where the micro-teeth are made of steel material. The cutting edge is made of non-alloy or low-alloy steel. Grooves are formed at the sharpened side, where ends of the micro-teeth are formed.
