The guy did say something to the effect of "I'm feeding my family by doing this, which is INSANE". So he understands that this is a fun novelty kind of thing, and has a good sense of humor. To be honest, how many tv shows actually show anything at all resembling what we do? None. So ya know what? I'd rather watch a guy grind out a funny ass 54lb sword and bust some junk to pieces with it, than Honey Boo Boo or "Me and My 90 Kids" or whatever.
A tv show that shows actual metalwork, and is probably a goofy good time? I'll take it!
The show is supposed to be fun and funny, and I do not believe at all that this will insult or hurt the knife community.
