Spark's(ummm, brain fart, I've gone back and forth from spark and sharp here, so whichever one is right should fillin the blank), who owns this site, also sells knife kits through One Stop Knife Shop. The Darrel Ralph kits are supposed to be a great place to start, and are going to be what I start with for my first folder. Fixed blades are easy enough(ha, just saying that now, shoulda asked me a few months ago), that I make them from scratch myself.
I'm same way as others here, will never do it full time, but it's something I enjoy, and that as a matter of "pride of the artiste", as my friend put it, has some levels that I will have to reach. I've learned a ton from various makers on here, and love that I can ask questions of some of the greats, such as Ed Fowler and Kit Carson, and they actually take the time to help out new makers such as myself.
Crayola is also right about it helping you know mroe about knives you buy then. It's definitely worth at least making a kit or two. Very rewarding, and very educational. Plus gives you a knife that you can carry and really call YOURS.
