Key features
- Bale-cutter knives to 1,500 mm, sections to 40 mm thick
- Polished low-drag edges — rubber releases instead of sticking
- 6CrW2Si for impact, SKD-11 where wear dominates
- Serrated and wave profiles for grip-free cutting
- Sets ground and balanced for rotary bias cutters

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 guide6CrW2Si
HRC 54–58 · Medium
Chosen when chipping is the failure mode, not wear.

Three things, in order: a polished edge (Ra 0.4 μm or better), a slightly larger edge angle so the blade wedges less, and a PTFE anti-stick coating if the compound is tacky. Tell us the compound and temperature and we will pick the combination.
Yes, with a tougher grade and a stronger edge angle. Steel cord eats standard edges — we use 6CrW2Si at HRC 54–58 and a 30°+ bevel for that work.
Yes. Send the drawing or a worn sample. Rotary bias-cutter blades and shaped guillotine knives are routine for us.
