Nothing against the others but I nominate Kevin Cashen for his in depth writings on the most difficult and controversial subject of heat treating.
Kevin Cashen
Both are amazing at what they do and very helpful awesome people! I count myself blessed to know them and we are a lucky bunch of dogs to have guys like this in the pound!
I also want to nominate,Nathan the Machinist.
His posts about hole drilling have helped me with one of the problem areas of my knifemaking,HOLE DRILLING.
NATHAN THE MACHINIST
I'm gonna give my nod to Kevin Cashen, but only because Bruce has already won it. I know I've learned a ton from both of them, and both (and quite a few others) are deserving of any recognition they get.
