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 guide6CrW2Si
HRC 54–58 · Medium
Chosen when chipping is the failure mode, not wear.
Read the full grade guideHSS M2 / M42
HRC 62–66 · Very high
M42 (cobalt) for heat resistance at very high line speeds.

Hardness versus toughness is the whole decision here. A very hard knife (HRC 62+) stays sharp but chips on impact; an impact-tough grade at HRC 54–56 bends instead. For recycled or nail-contaminated wood, we recommend 6CrW2Si at HRC 54–56. For clean plantation wood, a harder grade gives longer runs. Tell us your feed material and we will pick the grade.
A chipper head spins at 600–1,200 rpm. If the knives in a set differ in weight, the head vibrates, bearing life drops and cut quality suffers. We weigh and balance matched sets within ±2 g. It costs a little more per set and saves considerably more in bearing and downtime costs.
Yes. A double-edged knife gives twice the service life per blade because you flip it rather than resharpen it. The trade-off is a slightly higher unit price and a knife that is stiffer to set up. For high-consumption lines it is usually the cheaper option per tonne of wood processed.
Yes, in lengths matched to your peeler and in the corrosion-resistant grades veneer work requires, since green wood and steam create a wet environment. Tell us the peeler make and the log diameter range.
