Bury the hatchet. Meaning. To settle your differences with an adversary. Origin. The supposed language of Native Americans that we are familiar with is largely the invention of Hollywood scriptwriters - 'white man speak with forked tongue', 'kemo sabe' etc.
Hatchet is sometimes referred to as a small axe as it is meant to be used with a single hand, as opposed to an axe that needs employing both hands. What this means is that a hatchet is for smaller jobs and as such has often half the size of handle in comparison to an axe.
