Does he have a power hammer?
If he doesn't, and is making those blades by hand-hammering, don't ever piss him off...he's probably got an unbelievably strong hammer-like sucker punch.
Nice work...I really enjoy seeing stuff like this...I like blacksmithing, especially making knives from old garage sale hand files, so I can appreciate the amount of work (and skill) that goes into hand-making a blade...
