Material Description SKD11's steel grades are GB Cr12MoV in China, JIS SKD11 in Japan,

AISI / SAE D2 in USA, DIN 2X165CrMoV12 in Germany.

SKD11 belongs to mold tool steel, and it is also a kind of high-carbon alloy steel. It has both high hardness,

high strength, and abrasion resistance,

and its surface is precisely ground, which is suitable for making blades.

Chemical composition (JIS G4051) (C)% : 1.4~1.6

Crush Cut Knives

130T Unibody Zigzag knife

The 130 teeth zigzag blade is made of tool steel (SKD-11) imported from Europe, processed by well heat treatment to increase its mechanical properties such as toughness and wear resistance. The blade tip is precisely ground to maintain an equal tooth pitch and peak, the slitting edge will generate the zigzag notch, to facilitate tearing along the notch. The zigzag blade is suitable for easy-tear applications such as medical tapes.
