Sankaku Channel/chainsaw

Essentially a mechanized ax. The chainsaw consists of a belt of metal or diamond blades that is spun around by a gas powered motor or an electric battery. The use of the chainsaw traditionally is to cut down trees for logging uses. Non traditional uses include but are not limited to ice sculpture, killing zombies in the woods, and killing just about anything in the messiest way possible.
