Frequently Asked Questions (FAQs)

1. What are the knives on a jointer called?

The jointer consists of a worktable through which the revolving blade (called the cutterhead) of the tool protrudes.

2. 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.

3. What angle do you sharpen jointer knives?

If I remember correctly the angles for the planners and jointers are usually between 40 and 50 degrees, but Jeff was right different manufactures may choose different angles based on the machine characteristics and blade thickness and width so it would be safer.
