The show isn't for knife makers, it's for a broader audience or it stands zero chance of being renewed or making money and TV is a money business first. There has to be some contrived "challenges" like short time deadlines, serrations or splitting a bullet (sigh...) or making a Katana and whacking a body model to make it interesting for those that have no idea custom knife makers exist -- which is about everyone that may have watched it.
We as knife makers are a very small percentage and maybe 95 out of a 100 "ordinary" people have never heard of custom knife making. The exposure this show brings can help with that. I'm sure some viewers will not understand how much time it takes to make a good knife. I'm also sure some customer will want a knife that punches through steel drums. A five minute conversation with a new client will take care of that. If I watch a TV show on how Ninja's train, I don't think I'll become a Ninja after that with three hours practice. I also don't think many people will believe they can make a knife in 3 hours.
I understand the concerns makers have about broadcasting factual and accepted knife making techniques and results. We all want a realistic portrayal of the process and the performance a custom knife can give you. After talking to a few of the contestants, they feel good about the experience and how the producers are setting up the show and I trust their opinion.
Knife making has been a blacksmith, guild, trade or military closely guarded secret until WW2. Custom knife making didn't really become well know (relatively) until the 70's when it started to become more widely known. We can thank Lovelass and several others for that. There has been no other TV show like this and we can use the exposure, even if it isn't framed up exactly like we would prefer it to be done.
I think the amount of interest in custom knives will increase as will new makers coming into the craft. I don't see a downside to this even if it set up as an elimination style reality show. I thought the judges, the host and the overall feel of the show is respectful of the craft and the knife makers competing on the show. It's not a "how to" show, it's an entertainment show. I'd certainly film it and show it a little differently. I bet every knife maker would but for what it is as entertainment, I think they showed knife makers as humble, passionate and skilled craftsman and that was more important to me than most anything else.
