Axe

An axe (in UK spelling) or ax (in US spelling) is an implement consisting of a sharp metal or flint head on a haft, or handle, which is usually wooden. Axes can be used for chopping wood, as a ceremonial symbol, or, as is more common in the PPC, as a Weapon. Agent Laburnum received an axe as a present from the Official Fanfiction University of Redwall after the purging of That Series, and treasures it.

"Axe" is also a slang term for a guitar, but it's less common to kill people with those, unless you're Jim Steinman.
