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.

Typically 0.05–0.15 mm depending on the resin. Too wide gives tails and dust; too tight and the knives kiss and chip. Our matched sets are ground flat to 0.02 mm so you can set the gap once and trust it.
Glass-filled compounds need carbide. Solid carbide is brittle for granulators, so we inlay carbide strips on a tough steel body — you get the wear life without the catastrophic cracking.
Yes. Send them in pairs if they are a matched set — we regrind them together and mark the new height so your gap setting stays right.
