The classic piece of tattoo design, dagger through the heart, successfully manages to capture both our attention and our emotions. The real power of the image of a dagger through the heart is the combination of two symbols which are well known in their own right. The heart has long represented the seat of the emotions and the very core of a person. Similarly, the dagger is not just any weapon. It long ago became the stealthy weapon of choice for assassins since it was easily concealed and quiet. As such, it inflicted much more than just a stab wound, carrying with it an additional sense of betrayal and hurt, since the attacker had to be close to be effective. So, the heart-with-dagger tattoo is essentially the heart in great pain, perhaps mortally wounded, sometimes a love betrayed, and sometimes even a sacrifice made.
