刨子是一种木工工具，用来刨直、削薄、出光、作平物面。

将刨刃安装在坚实刨身上，再将整个刨身再工件上移动可以削出厚薄均匀的刨花。由于刨身具有一定长度，从而自然的切削木材突出的部分，加之刨刃固定成一定的角度，刨过的表面能够达到均匀平滑。

大多数刨子是向前推动使用的，也有部分是用拉的，例如日本的刨子。

A hand plane is a tool for shaping wood. When powered by electricity, the tool may be called a planer. Planes are used to flatten, reduce the thickness of, and impart a smooth surface to a rough piece of lumber or timber. Planing is used to produce horizontal, vertical, or inclined flat surfaces on workpieces usually too large for shaping. Special types of planes are designed to cut joints or decorative mouldings.
