But yeah if you own one.... DUH, use a Domino. I have a partially competed desk for my Wife, I am creeping along on it, mostly because of all the M&T crap that it represents. I have made several of this same desk since having a Domino, and to tell the truth through tenons are vastly overrated. The non through Domino done ones look very nice. If they are blind, then doing real M&T's in the presence of a Domino is just Masochism.
