Blade Arte + Science

THE PRECISION KNIFE SHARPENING PROCESS

1. GONIOMETER

The initial blade angle is measured using the goniometer. The edge angle is objectively verified.

2. INITIAL BESS TEST

We use the BESS test to measure the initial blade sharpness.

3. PROJECTION DISTANCE

The knife is clamped and the projection distance is measured to calculate the sharpening edge angle.

4. SOFTWARE GUIDED

All the collected data is entered into our software for milling calculations.

5. SETTING CALIPERS

Calipers are set using software values to ensure precise angle.

6. CALIPER MEASUREMENT

Calipers are then used to set our equipment. We are not free-handing.

7. CBN MILLING

Now we begin milling the knife edge on cubic boron nitride (CBN) abrasive.

8. KNIFE DEBURRING

Then we debur the knife on a felt wheel. This step removes weakened steel to retain the blade's edge.

9. FINAL BESS TEST

Lastly, the sharpened knife is BESS tested to measure the final sharpness.
