I have a stacked cutter set that came with 1/16, 1/8, 3/16, and 1/4. I’m trying to think if I ever needed something in between and I can’t think of that happening. The set also came with a bunch of shims which is handy if you are using two cutters to make a tongue or short tenon. I think I’d still go with a stackable set rather than one adjustable cutter. I think the set is more versatile.
Someone I consider a master woodworker once told me that a master woodworker is not someone who never makes mistakes. He is someone who is able to cover them up so that no one can tell.
