How our blade reverse-engineering works

Most buyers come to us with a blade, not a drawing. That’s exactly what we built this service for. When you reverse engineer a blade from a sample, we don’t guess — we measure. Every critical dimension, bevel angle, hardness, and material grade is captured, then turned into a drawing with GD&T you actually own.

The 4-step reverse-engineering process

• 1. Ship the sample. Send your worn or broken blade (freight covered by you; sample redraw is free).
• 2. Measure & scan. We profile geometry, edge angle, coating, and hardness on metrology equipment.
• 3. Return the drawing. You get a drawing with GD&T — clear, dimensioned, yours to keep.
• 4. Free sample blade. We supply one working blade made to the redrawn spec so you can prove it on your machine.

Why reverse-engineer instead of re-ordering abroad

When the original supplier disappears or the drawing is lost, buyers are stuck. Our reverse-engineering service removes that block: a free sample, a drawing you control, and a 30-day production lead — versus the 35–45 days typical overseas. For obscure or discontinued industrial cutting blades, this is often the fastest path back to a running line.

What we can reverse engineer

Circular slitter blades, shear and guillotine blades, granulator and pelletizer knives, circular and straight knives, food-processing blades, and most custom geometries in D2, SKD11, HSS, stainless, or solid carbide. If it cuts, we can redraw it.

Works the same way for air scissors heads: worn cutter heads and mask machine blades are reversed into drawings the same way.

Measuring the worn blade first? The six dimensions that define a blade — and the tools that get them right — are in our guide to how to measure a cutting blade without a drawing.
