Damn you, -BerZeKeR-. You made many nice axe icons, I'm spoiled for choice as to which one to use.
Icon itself, ah. The green glow, is it just meant to be generic (lemon juice my foot) and decorative? If it is, then it looks fine. On the other hand if you want to make the glow symbolize something, like acid, or poison, that would be nice too, but then more work will need to be done.
Oh noz! :]
