Axes are about the easiest thing to freehand, that's why there's so many of them already on the site. If it's really necessary to make another one ATOP of the heavy archive here and the ones already in-game, you should at least try to make a good one yourself. A screenshot of this just couldn't look nice - the stone texture is too dark and monotone to capture any proper lighting from the normals (which by the way you should probably re-calculate), unless of course you edit the screenshot. I dunno, I suggest you do one of those, or request an icon. Very simple, I'm sure someone with a program as free as GIMP could do it.
