Z, here are the URLs for some of the above mentioned videos:
Texas Knifemaker's Supply - Loveless and others like Ed Fowler, Jim Hrisoulas, Wayne Goddard and more. From comments on this forum though, I'd recommend you order via the phone rather than their website. Personally I've never had any success ordering off their site, and I've really tried. Other supply houses have videos too, of course.
Gene Osborne's video is fantastic, but for this particular knife he uses a grinding jig that probably isn't practical for most beginning makers. However, there are many other tips and tricks of construction that make this one of the best out there as far as I'm concerned. I watch it over and over. Plus, Gene's a gem of a human being.
Knifeart.com doesn't seem to have any videos, but their book selection is excellent. I could spend my whole allowance right here!
Finally, I just did a Google search for "knife making video" and came up with this
eBay auction . I've never seen this video before and the bid is over $20 now for a one-hour tape, so not the best deal on this list. But it's one good way to find stuff.
To find out if knife making is something they might want to do without investing a lot of cash, some people have bought pre-ground blades or knife kits from one of the supply houses like TKS. I haven't built a kit but it seems like it might be worthwhile if you have any doubt whether this is something you'd get into. Frankly though, before you've finished the first knife you'll almost certainly be planning the next...
Good luck! Keep reading here too, this is the most helpful bunch of people on Earth and they'll share a wealth of experience with you.
