North of the Border
While this particular video does not show all the faces of the joint, in other live woodworking shows (I have been to two in which he was present), he handed the joint to the audience and it was a gap free joint. No tricks and no shortcuts.

The two dovetail teachers I know cannot cut a joint like that in 5 mins even in pine or any softwood. Anyone who doesn't believe me can grab a scrap and try it.

Rob Cosman can cut as fast but he uses a chisel in his process, dividers, too.

Paul's skills are undisputed in camera or in person. Second to none, if you ask me, as a skilled dovetailer myself.
