I have a large bowie (12" blade) and was wondering where I could send it out to for some modifications.  Things like adding a fuller, some jimping on the spine, and then repolish it to it's current mirror shine.  Thanks in advance.

Northern Knives in Alaska did some work for me. I would use them again if I needed more work done.

Judging by watching Forged in Fire a fuller would pretty much require machining or reforging.  Either way the knife probably would need to be annealed, modified, hardened, Tempered finished and reassembled.  Machining without annealing would require pretty awesome cutting tool I'd imagine.

I think it would be more trouble than it is worth and you may still not be happy with the result.

I suppose that's possible, I never really thought about it.  Still going to see if it's possible though.

Josh at razor edge knives does some great work, I've had some knives bead blasted, cerakoted and finger choils cut in, has a great reputation on bladeforums as well.
