dagger

A dagger is a short knife with a pointed and edged blade, used as a weapon. It is the tool of choice for many assassins for its easy-to-hide size, yet capable of dealing silent and lethal blows to the enemy. The main difference between a dagger and a normal cutting knife is that daggers usually have blades on both sides like a short sword, they come to a point at the end rather than rounding out for stabbing, and are often slightly longer than a normal knife.
