Materials used for this blade
SKD-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 guideHSS M2 / M42
HRC 62–66 · Very high
M42 (cobalt) for heat resistance at very high line speeds.
Read the full grade guideSolid Carbide
HRC 64–70 · Extreme
10–20× tool steel life, but brittle and not resharpened many times.

Usually the edge is too coarse or the bevel is wrong for the fabric. A polished edge with the correct bevel angle slices between the threads. We grind cloth knives to Ra 0.4 or better and mark the bevel angle on the blade.
Yes. Send the drawing or a worn sample — curved and shaped trimming knives are routine work, and we can regrind your worn ones back to profile.
Glass fiber eats steel — use solid tungsten carbide. It lasts many times longer than HSS on fiber and cannot be resharpened as easily, so for most fiber lines carbide still wins on cost per cut.
