An axe is a heavy weapon used in the Medieval days of the United Kingdom, as well as other eras of history and in fiction. The user holds a long handle in the other and can swing the double-bladed weapon either way to chop and slash foes. In Sonic the Comic, axes were a large part of The Legend of the Golden Axe series. The titular Golden Axe is a large, magic axe that gives the bearer additional strength and has also been seen used as a way to bring Dark Guld to life (although it was not completed). Gilius-Thunderhead and several other dwarf warriors also carry axes.
An another axe was seen on the Hell House Ride in the Carnival Night Zone. A mechanical knight used it to try and kill Knuckles the Echidna but it narrowly missed him. Instead, the axe lodged itself in the bag of the carriage; fortunate, as the echidna used the axe to latch back on to the rollercoaster tracks when it suddenly ended.
