Knife and dagger tattoos are regarded as cool by many school going children. There are many variations but all have one thing in common – the image of a dagger or a knife. Knives and daggers can be tattooed alone or they can supplement a bigger image to tell a story.
A dagger or knife design have shown up a lot in tattoo themes, since the dagger has been used in ceremonies since long before modern civilization. Daggers were thought to be first used by the Aztecs to cut the beating hearts out of their human sacrifices as a way to pay their respects to their Gods, so to them a dagger represented the power of the Gods.
