The grass cutting sword as it's most commonly known has the ability to control the winds. According to legend it got it's name when a warrior went to battle a treacherous warlord who attempted to kill him in a grassy field by setting it alight.

Attempting to mow the grass to make his escape the warrior discovered it's ability to control the winds and used it to redirect the fires at the warlord.
