Frequently Asked Questions (FAQs)

1. How sharp should jointer knives be?

We recommend sharpening to roughly 600 grit. Any finer and the resulting edge gained will only last a short time. Use a diamond hone to refine the edge and remove any burr from the back and bevel of the jointer or planer knife.
