Just wondering what grit finish do you take it to before you HT. I will be hand finishing after HT except for the sharpening.
 
FWIW, I only do carbon, and I only go to 220 grit lengthwise, as post heat treat I come back with 80 grit to cut the edge down further from .030 to whatever I need for the application. I do hand finishing as well. Some guys go to 400, maybe 600. I've never seen the need, unless your pre-heat treat grind is 95-99% of your post heat treat finish, then I would go to 400. Less work post heat treat.
 
Have a read in the stickies. There is this and many more questions answered up there.
 
Thanks Willie, I have already read the stickies, just looking for different perspective on it.
