Big, heavy, khuk, like an axe, smooth, controlled, swing, just enough oomph to impart good momentum, but more focus on an accurate strike. Smaller, lighter, khuk, machete like swing, not noticeably harder, but noticeably faster, with more of a wrist snap at end of swing. Busted an axe handle or two back when I was a strapping young lad, but between my father and uncle, soon learned the error of my ways. Haven't busted a chopping or cutting tool since, but have worn some out.
