Razor

Thy tongue deviseth mischiefs; like a sharp razor, working deceitfully.

In the same day shall the Lord shave with a razor that is hired, namely, by them beyond the river, by the king of Assyria, the head, and the hair of the feet: and it shall also consume the beard.

And thou, son of man, take thee a sharp knife, take thee a barber's razor, and cause it to pass upon thine head and upon thy beard: then take thee balances to weigh, and divide the hair.
