Brian,
Thanks for the article. I also read Old Jimbo's articles on axes. Unless i missed it, i havent read anything that describes what edge shape works better in which type wood so maybe its just the bevel to cheek width and its angle or rate of increase, if i am describing it correctly.
There are many books that have diagrams of different edge configurations. You pretty much just described it there though. In general, the harder the wood, the more thick and convex the edge generally is.
What I have done in the past is to take different axes through different stages of grind. Thicker to thinner. Trying them in different types of wood, when I come up with one that I really like the performance of, I make a wooden jig for future grinds.
It is amazing how subtle it can be sometimes. You grind an axe to a jig and it looks "close enough." Go try it out and it is not up to par. Go back and grind a bit more and presto!
Does the quality of a S&N axe vary greatly, from what i have read (mosty at BF) GB is good, Wetterlings is hit or miss.
I have ground quite a few of them now. The edge on them is not setup well, and is rather coarse. Pretty typical actually. The head profiles have seemed to be pretty darn consistent. I had one that had a touch more material in one spot, but I ground it away to match. I am very happy in that aspect.
I have had only ONE that I was not happy with. The handle grain was way out of whack. I will more than likely document the defect and part with it at a lower cost. Either that or see if S&N will exchange it. I am kind of curious how they will react to it. Being a small guy, they will probably just blow me off. But, we will see.
When I bought my first S&N from a large dealer, I asked them to please check the handle grain for me. Three days later, sales connected me to technical support, to tell me that it is a "production axe" and I can't expect it to be perfect. I told them that it was a $50 production axe and I can expect more than a $20 hardware store axe, including a proper handle. That one arrived okay.
Long way of saying.....I think it is still too soon to tell. I can keep you posted as I get more and more, if you are interested.
