Since this has apparently sparked a lot of interest, may I also recommend "An Ax to Grind: A Practical Ax Manual", put out by the U.S. Dept. of Agriculture, back when our government did useful stuff. A lot of really useful information for those who may not have much experience with axes, as well as those who grew up with them. I'm one of the latter, and when I found this a few months ago, it went into my list of reference material. Can't know TOO much about a tool that can cut yer leg off, iff'n ya ain't careful.
