Paper Guillotine Knife
Guillotine and trimming knives for printing houses and paper converters. Made from W18Cr4V (T1) or W6Mo5Cr4V2 (M2) high speed steel, the edge stays sharp through long runs and leaves a clean, burr-free cut on coated paper, board and film.
- Drawing: required for every order (PDF / DWG / sketch) — the drawing governs
- Material options: W18Cr4V (T1) / W6Mo5Cr4V2 (M2) high speed steel
- Hardness: HRC 60–64
- Edge type: Straight / circular blade (optional)

Machines these blades are made for
Guillotine knives are matched to the clamp bar: body width, thickness and hole pattern differ by brand, and the length alone will not tell you whether the blade mounts. These are the machines we grind for every week.

Frequently asked questions
Which paper cutters do these guillotine knives fit?
Sizes are matched to Polar 66-155, Wohlenberg 76 GW / 92 / 115 / 137, Perfecta 92 / 115 / 132, Schneider, Maxima, Ideal and Itoh models. A blade fits only when length, width, thickness and the hole pattern all match the clamp bar, so tell us the machine model and we confirm the drawing before production.
Should I choose T1 or M2 steel?
T1 (W18Cr4V) is the standard choice for uncoated paper, board and general printing work. M2 (W6Mo5Cr4V2) holds an edge longer on coated, laminated or recycled stock, which is more abrasive. Both are supplied at HRC 60-64; if you are unsure, tell us what you cut and we recommend one.
How do I know when the blade needs resharpening?
The cut edge starts showing fuzz or fibre tearing instead of a clean slice, and operators compensate by increasing clamp pressure. If the blade has four ground edges, rotate to a fresh edge first; when all edges are used, send it back for resharpening. A blade normally takes 5-10 regrinds.
What is the smallest order and the lead time?
One piece can be sampled so you can test it on your machine. Standard sizes ship in about 7 days; blades made to a new drawing take 15-25 days after you approve the drawing.
