To comment on LittleSpartan's post (not gonna quote the whole thing), I've seen his knives in action, and to say he's a hobbiest does not reflect his knife quality. And after reading your post, I'm more inclined to purchase his knife for two reasons: (1) How rewarding would it be for him to know that one of his knives aided my survival in a "Worst that Could Happen" situation, and (2) What better customer service than to sit down with him over a beer and discuss MY knife design?
Didn't mean for hobbiest to come off wrong if it was informally and indirectly offensive. I am not knocking on his work, it looks nice, but after reading other post by others, I share similar concerns, warranty, established position. Etc.
I have a GSXR and a Sportster, but I've built a Waltz Hardcore Custom Low/Wider. Among a few other bikes. I have also bought 2 customs built by now gone individuals, was just posting on my own experiences with custom work. One guy passed away, another uprooted and is in the Philippines now I think last I heard?
But again that duality of quality serves good and bad, because my customs are AWESOME, granted one is my dads, and one my uncles now, because they have the time and ability for upkeep. But their quality was amazing. I've also run into shaddy "builders" if thats what you'd call them.
And its been a really crappy experience. From shops in Long Beach who were suppose to do the proto typing for my 68 camaro's body parts in Carbon Fiber, like the fenders, trunk lid, hood, and wider body add ons...to also doing my cage. Two years off my life, waiting, and when I went to get my car after having enough of the run around, it was sitting outside on wood blocks, RUSTING. exposed to the elements.
Now adays I have begun a restomod with my cousins, a team effort on a Dynacorn Body, did the cage work and reloc of the firewall myself, indented and sunken AC Cobra Gas cap out back, and as a group we are saving $ for the LS3 we want to sit in it.
Sometimes if you want something done right, do it yourself. Or have someone you trust

Hahaha.
I didn't mean to come off as a jerk if I did, I am just saying that if the guy does it on the side and if you don't know the quality of his work to well, caution. However, on side hobbiest isn't a bad thing. It could mean higher quality work, lower volume, more time and attention to detail! Know what I mean?
I no longer go to shops for my car, bike, or truck work. I do everything myself. That meant selling one of my customs to buy and furnish a new snap on box, among many other things so I could handle working and tackling my own stuff.
But in anycase, I apologize. And hope all else goes well for you! Let me know how the knife turns out if you go your friends route, it does look amazing!
