A Knife can refer to a variety of short-bladed weapons used throughout the Inner Sphere. Easy to conceal and use, some are built for maximum damage while others are designed to be thrown. The primary difference between a knife and a Dagger is that the latter generally cannot be thrown effectively. A Bayonet is essentially a dagger which is designed to attach to the end of a rifle.
