What Mike said, I only use a limited amount of barstock, the rest is forged.
The way I'm leaning now is on must larg hunters, 3/16 or a little larger at the guard with distal tapper to the point. If I order any more stainless I'll get both 3/16 and 1/8. The 3/16 would be for larger hidden tang knives, with a lot of grinding to get the distal tapper I want. I have made a 10" kitchen knife out of 1/8", but any larger or any rougher use I'd want a little more meat at the ricasso handle juntion area.
Personal preferances aside, 1/8 is good for about 99%of small to mid size hunters.
