To bury the hatchet means to create peace. With hostilities at an end, the hatchet was no longer needed, and therefore could be disposed of. Now a merely figurative expression, the phrase is based on an actual practice of North American Indians.

When negotiating peace, they buried all their weapons; their tomahawks, scalping knives and clubs.

Apart from showing their good faith, simultaneously it made it impossible for them to go on fighting.

 "埋了斧头“意味着创建和平。敌意已经到头了，斧头也没有了用武之处，所以应该搁置起来了。这是个形象化的表达，这个俗语是建立在北美印地安人的实际做法上的。

当和平谈判时，他们会把所有的武器：斧钺勾叉，棍棒等全部掩埋。

除了显示他们的诚意外，同时，这样做他们也不可能继续战斗。
