A
dagger is essentially a special form of
knife, where the tang
? is placed along the center line of the blade
?. A dagger is much more than an ordinary knife a
weapon made for thrusting rather than a
tool for slicing and cutting. Historically daggers were important secondary weapons in
Europe during the
Middle Ages and the
renaissance.
Often a dagger is fairly long, and some may verge on being of sword length. Most daggers are double edged, although there are exceptions.
A modern version of the dagger is the bayonet?, which becomed a spear type weapon when mounted on the barrel of a rifle.
