Perhaps it was you who I talked to before about the grind in. You're in the northern LP?
Depending on your design that may be a good route to go. Just leave yourself enough room to get all of the finish work done and take into consideration any areas the plasma may affect heat treat of your steel. I'm not familiar enough with that machine to know if that is a factor. They don't do any heat treating there so you'll want to have it done when you buy the steel.
You can also take into consideration any special handle materials you might want to use, that may not be offered. They have a huge selection of micarta and woods, just like their knives normally have, but sometimes you just might want to use something outside the ordinary for them. My brother had hand carved some G10 ahead of time for one of the knives he made, that way he could save time but still get it done. I'm working on my own special blend right now for my next knife. I will be sure to post more pictures this time.
