worth the money?


I didn't think so when I got my 8" jointer. I've seen no reason to change my
opinion either.

Logically, I'd think the spiral knife would be better at cutting
because there is more blade and the blade is slicing at an angle. Does
that $400 include lifetime sharpenings? Straight planer knives are
easy to sharpen.
