This is the first knife I'll see to completion. Used a Gough file jig to get the bevels. Still having trouble getting perfect plunge lines, although this time I used a chainsaw file to start them which gave me much better results. Was able to get working edge to .025 ± .01, which should suffice for heat treat? I'll be sending off for Darrin Sanders heat treat. I still have to hand rub the finish. I have ferric chloride coming. What grit should I go to in order to get a good acid finish? 220, 400? Anything else I should do before heat treat? Thanks.

def an intersting shape. it looks like the blade got flipped on its spine during the grinding process.
 
I would go to 400grit, pre-HT. Post-HT go back a grit, remove all traces of the 400grit, and then go back to 400grit. Be sure to remove all the marks of the previous grit as you progress up through the grits. It'll make less work for you if you do 90% of your sanding pre-HT as hardened steel won't be as easily sanded.
 
120X is fine before H/T. When you get it back you'll have to remove a little decarb. anyway. If you're gonna etch it in FC after H/T, a good even 220X finish is good enough. Anything higher will just wash out in the etch anyway. Here is what I suggest;
1. Finish to 120X.
2. H/T.
3. Remove decarb. with 120X.
4. Finish to a nice even 220X.
5. Etch.

I don't know what I was thinking...

This sounds much better.

Thanks Darrin. Will take this route. Have never used FC so I'll make sure to look around for good tutorials. Should have this shipped to you by next Friday. Definitely appreciate the advice.
 
Give me a call sometime this weekend and I'll walk you through how to etch a blade. Try to call between 9am & 9pm central time. My number is listed below.
 
Thats a hell of a good looking knife you got there. Love the wharnies!
