battleaxe

“The Rondolim appears to be an ancient, rusted battleaxe, worn and bent from years of use.  The owners of most weapon shops would be ashamed to have it in their junk piles.  When in the hands of a dwarvish warrior, however, the Rondolim takes on its true form.”  (Stephan Peregrine, Treasure Vault by Steven D Howard, Blade/Flying Buffalo, 1984.)
