传说，有一年鲁班接受了一项很大的任务——建筑一座大宫殿。这需要很多木料，但是工程限期很紧。鲁班的徒弟们每天都上山砍伐木材，但是当时还没有锯子，只有用斧子砍，效率实在是太低了，而且徒弟们每天累得精疲力竭，可是木料还是远远不够，耽误了工程的进度。那个年代，完成不了奴隶主的任务是要受重罚的，鲁班心里非常着急，就亲自上山察看。上山的时候，他偶尔拉了一把长在山上的一种野草，一下子手就被划破了。鲁班很奇怪，小小的一根草为什么这样锋利？他把草折下来细心观察，发现草的两边都长有许多小细齿，他的手就是被这些小齿划破的。既然小草的齿可以划破我的手，那带有很多小齿的铁条应该可以锯断大树吧。于是，在他的想法加上金属工匠的帮助下，鲁班做出了世界上的第一把锯——一把带有许多小齿的铁条。他用这个简陋的锯去锯树，果然又快又省力，锯就这样发明了。
