Materials used for this blade
Cr12MoV
HRC 58–62 · High
Widely used, well understood grade. Good balance of cost and life.
Read the full grade guideSKD-11 (D2)
HRC 60–64 · Very high
Longer life than Cr12MoV at higher cost. The default upgrade.
Read the full grade guide9CrSi
HRC 56–60 · Medium-high
Economical and forgiving. Common for large straight knives.
Read the full grade guideSolid Carbide
HRC 64–70 · Extreme
10–20× tool steel life, but brittle and not resharpened many times.

Usually one of three things: the blade has worn past its sharp life, the edge angle is wrong for your board grade, or the top and bottom knives are not a matched pair. Thin blades (0.9–1.2 mm) with the right bevel solve most crush complaints. Send us the board flute and liner weight and we will set the angle.
If you run virgin kraft liner, tool steel is fine and resharpenable. If you run recycled liner with sand and filler content, carbide pays for itself in weeks — it holds the edge 10–20 times longer against that abrasion.
Yes. Send a drawing or one used knife. We match the tooth pitch, depth and gullet radius so the slot comes out clean and the waste strip drops free.
