Guy Himber gave me this recently. It is a Brickarms prototype made for CrazyBricks upcoming Munchkin Kickstarter project. If you aren't familiar with Munchkin, it is a fantasy-based comedic card game where you fight each other using funny weapons and armor. The creator of the game is a big LEGO fan and Guy Himber was able to obtain a license to make minifig items based on the game. This axe is on the cover of Munchkin 2: Unnatural Axe.
