Koncerz
A koncerz is a type of sword used by Polish-Lithuanian hussars in the Renaissance period. It is a thin and long thrusting sword, generally used by a type of heavy cavalry and optimized to defeat body armor, but not used to cut or slash.
The koncerz originated from a medieval sword and appeared at the end of the 15th century when it was about long, and relatively unwieldy compared to single-handed thrusting swords designed for use by infantry. By the late 16th century it had increased in length to a typical overall— blade—and had a more optimized weight distribution and balance. The koncerz was used more like a lance while on horseback; it provided a rider with a very long reach in a relatively compact format suitable for a sidearm. Since it was optimized for thrusting, the koncerz had no cutting edge, only a very sharp point; the blade itself was triangular or square in cross section in order to be more rigid.
The closest western European equivalent is the estoc, or "tuck".
