Key features
- Drawing or a used sample — both routes accepted
- Material recommendation from an engineer, not a salesperson
- Drawing confirmed in writing before any steel is cut
- Prototype tooling made in-house, not outsourced
- Your drawing stays yours — no reuse, no resale to competitors

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.
Read the full grade guide9CrSi
HRC 56–60 · Medium-high
Economical and forgiving. Common for large straight knives.
Read the full grade guide6CrW2Si
HRC 54–58 · Medium
Chosen when chipping is the failure mode, not wear.

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.
