How to Reverse-Engineer a Worn Cutting Blade (No Drawing Needed)
No drawing, no supplier, edge gone. You do not need a CAD file to get a perfect replacement blade — here is exactly how it works.
You have a blade that works — but no drawing, no supplier, and the edge is gone. This is the most common starting point for a custom blade enquiry, and it is exactly what our reverse-engineering service is built for. You do not need a CAD file to get a perfect replacement.
What you send us
Two options, both fine:
- A clear photo of the worn blade on a flat surface, with a ruler or caliper in the shot for scale. Good enough for a first quote.
- The physical worn blade by post. Best for tight-tolerance parts — we measure it on our own equipment and capture every fillet, bevel, and hole.
How the process works (4 steps)
1. Send the sample or photo. Use the contact page and attach it — drawings and photos are welcome.
2. We measure and redraw. Within 24 hours we assess the part and, for physical samples, produce a full drawing with GD&T (geometric dimensioning and tolerancing).
3. You approve the drawing. Nothing is cut until you sign off. This is also where we confirm material grade and edge treatment for your application.
4. Free sample, then production. We make one blade free of charge (you cover freight), you run it on your machine, and once it performs we move to the 100-piece production order.
What you get back
A drawing you actually own — stored on file so every future re-order is identical, and so a “worn blade with no paperwork” never becomes an emergency again. For many customers this drawing archive becomes the reason they keep reordering from us.
Free sample, even for reverse-engineered blades
The same free-sample policy applies: sample free, freight collected, no spec too big. It is the fastest way to prove a replacement matches the original before you commit to a run.
Start now: photograph the worn blade and send it from the contact page.
Next step: if the worn part is a mask machine blade or an air scissors cutter head, those pages list the standard sizes to compare against.
