Custom Industrial Blades — Made to Drawing

If your blade is not in our catalogue, send the drawing or a used sample and tell us what it has to cut. We confirm the geometry in writing, recommend the material and quote.

Applications

Obsolete machine blades

The original maker no longer supplies it — we make it from your worn part.

Non-standard machine builds

Blades for prototype or custom-built equipment.

Performance upgrades

Redesign to fix chipping, sticking or short life.

OEM supply

Private-label blades under your own brand.

Fitting your machine, and buying a replacement

You do not need a drawing to start. A worn blade, a photo with a ruler in it, or the machine brand and model is enough for us to quote. Most custom jobs begin with a used sample: we measure it, quote from the measured figures, and make a test set before any production quantity.

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 guide
SKD-11 (D2)
HRC 60–64 · Very high

Longer life than Cr12MoV at higher cost. The default upgrade.

Read the full grade guide
9CrSi
HRC 56–60 · Medium-high

Economical and forgiving. Common for large straight knives.

Read the full grade guide
6CrW2Si
HRC 54–58 · Medium

Chosen when chipping is the failure mode, not wear.

Frequently asked questions

Best: a 2D drawing with dimensions, tolerances and material. Second best: the used blade, or a photo of it next to a ruler with overall dimensions. Third: the machine make and model plus what material it cuts. We can work from any of the three, but the quote gets more accurate and the first prototype more likely to be right, the better the input.
Usually yes, and this is where we add most value. Tell us how it fails — chipping, cracking, dulling too fast, material sticking, or cut quality dropping. Each points to a different fix: chipping suggests a tougher grade or a larger edge radius; fast dulling suggests a harder grade or a coating; sticking suggests a surface treatment. Send the failure mode and a photo and we will propose a specific change.
Yes. We do not reuse a customer drawing for any other buyer and do not resell a custom profile to your competitors. If you need a written non-disclosure agreement before sending drawings, we will sign one — tell us at the enquiry stage.
We confirm the drawing in writing before cutting steel, which removes most of this risk. If a piece arrives outside the agreed drawing, we remake it at our cost. If your drawing itself was wrong, we will tell you what to change and quote a revision — we would rather explain than charge you twice for the same mistake.
One of three things: a drawing, a worn sample, or a photo with a ruler in it plus the machine brand. Any one of them is enough to quote. A drawing is fastest, a sample is most accurate.
Yes. Most custom jobs start with one test set. Run it on your own line, and if the edge life is right, order the production quantity. Nobody should have to commit to a full run on an unproven blade.
Yes, if you need one. Send your own document or ask us for a simple mutual NDA. Drawings stay with us and are not shown to other customers.

Not sure which blade fits?

Send a photo of the blade you use now with a ruler next to it. We will tell you the grade and the edge angle.
