Knife tattoo designs are a theme that reoccurs all the time and cuts across many different era and themes. It is used in Aztec tattoos because knives are what was used to cut the heart out of a person and serve it as a sacrifice to the gods. Knife tattoos are also frequently used by those who consider themselves to be rebels. This is because the knife has been a long standing symbol of rebellion and treachery ever since Julian Caesar was assassinated with one.
But knife tattoos are seen more in military designs than any other tattoo design.
This is because knives are the perfect weapon for close combat as it is small, quick and silent. Those people who have served in the United State’s Special Forces are more likely to get a knife tattoo.
Knife tattoos are also seen as noble instruments of divine intention, much as swords are. This symbolism dates back to the Crusades when knights learned that the dagger was a great secondary weapon to wield in case they didn’t have the time or the room to draw their sword. Knife tattoos also represent speed, tenacity, aggression and a noble death at the hands of an enemy.
