Smith's Bible Dictionary 
Saw. Egyptian saws, so far as has yet been discovered, are single-handed. As is the case in modern Oriental saws, the teeth usually incline toward the handle, instead of away from it, like ours. They have, in most cases, bronze blades, apparently attached to the handles by leathern thongs. No evidence exists of the use of the saw applied to stone in Egypt, but we read of sawn stones used in the Temple. 1 Kings 7:9. The saws "under" or "in" which David is said to have placed his captives were of iron. The expression in 2 Samuel 12:31 does not necessarily imply torture, but the word "cut" in 1 Chronicles 20:3 can hardly be understood otherwise.
