Schneider Guillotine Knife Replacement Blades

Q: Can I use a Wohlenberg blade on a Schneider 115?

No. The Wohlenberg 115 blade is 1395 x 125 x 12 mm; the Schneider 115 is 1350 x 144 x 10 mm. It is 19 mm too wide for the clamp and 2 mm too thick to enter the holder.

Replacement knives for Schneider Senator cutters, in W18Cr4V (T1) or W6Mo5Cr4V2 (M2) at HRC 60–64. Two things decide fit on a Schneider: the 144 mm body width and the 10 mm thickness. A Polar or Wohlenberg blade of the same length will not clamp.

Schneider models and sizes we grind

Model	Size L × W × T (mm)	Size (inch)	Notes
115	1350 × 144 × 10	53.15 × 5.67 × 0.39	144 mm body, 10 mm thick
Senator 76 E	900 × 100 × 10	35.43 × 3.94 × 0.39	Same 900 mm length as several Wohlenberg models, different width

The 115 problem: three brands, three different blades

“115” on a paper cutter means the cutting width in centimetres, not the blade size. Three machines that all call themselves 115 take three different knives, and buying on the model number alone is the most common way to end up with a blade that will not mount.

Machine	Length	Width	Thickness	Interchangeable?
Schneider 115	1350 mm	144 mm	10 mm	Reference
Wohlenberg 115	1395 mm	125 mm	12 mm	No — narrower and thicker
Itoh 115	1410 mm	150 mm	13.7 mm	No — 60 mm longer, 3.7 mm thicker

Measure the old blade across its body, not along its edge. The body width and the clamp thickness are what the holder actually grips; length only decides whether the blade reaches both sides of the stack.

Frequently asked

Can I use a Wohlenberg blade on a Schneider 115?

No. The Wohlenberg 115 blade is 1395 × 125 × 12 mm; the Schneider 115 is 1350 × 144 × 10 mm. It is 19 mm too wide for the clamp and 2 mm too thick to enter the holder.

Is the Senator 76 E the same as a Wohlenberg 76?

The length matches at 900 mm, the width does not — 100 mm on the Senator against 125 mm on the Wohlenberg. Same length, different body, so the blade will not clamp.

Do you have T1 and M2 in stock?

Common Schneider sizes are held in both grades. T1 is the usual choice for coated and abrasive stock; M2 survives nicks better on recycled paper and thick lifts.
