Matt,
Kits come pre-heat treated. So you don't need to worry about that.
However, they aren't what you'd call a high-performance blade. They aren't really that much better than a knife you'd buy over the counter.
They do sell some blanks of ATS-34 or damascus. There you are looking at spending $50 - $200 on a blank.
Still I'd start with a couple of kit knives and keep them for yourself.
Then ask here on this forum if there is a maker that will make you a blank. Then you can use some fancy materials and have a really, really nice knife.
Probably the third step will be to buy some steel and try it from scratch.

PS Roger, don't care what you say, you still have me beat!
The LN tank was bad. It needs to get re-evacuated. I lost $80 of LN in 3 weeks. re-evacuated is only about $100, but I can't find anyone local!!!
