After every blade is sharpened, it must pass our rigorous five-point inspection before we dip it in protective coating and return it to you.

Our skilled sharpeners inspect for:

1. Edge quality and point sharpness-each tooth is visually qualified
2. Concentricity - within .002
3. Plate runout - within .005
4. Tooth runout - within .005
5. Tolerance of the various tooth geometry

Send us your blades for sharpening, and if you don't agree it's the best, we'll fix it! Test your newly sharpened blade as soon as you receive it, and if you're not happy with the result, return it right away with a sample cut of material and we'll re-sharpen it to your satisfaction at no charge. And we'll credit you for the original sharpening.
