Is "knock it" drop by accident or hit it? I don't get it.
ex)...A carpenter, unable to find his best saw, suspected that his neighbor's son had stolen it......But when the older man found the saw behind his own workbench, where he had accidentally knocked it, he colud no longer see anything at all suspicious in his neighbor's son...
He hit it and it fell off the workbench.
