Hegyestőr / estoc / koncerz
Hegyestőr / estoch / koncerz swords were formidable late Renaissance cavalry swords for piercing chainmail armor, used by the Hussars mainly in Hungary and in Poland. They appeared in the 16th century but they were used even in the 18th century as well.
The koncerz originated from a medieval sword and appeared at the end of the 15th century when it was about 1.3 meters (51 in) 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 1.6 meters (63 in) overall—1.4 meters (55 in) 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 (the typical primary weapon of hussars was a very long lance). Since it was optimized for thrusting, the concern 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 theestoch, or “tuck”.
They were worn on the saddle just like a similar weapon, the so-called “pallos” that was used for cutting. The swords here are from the 17th century, except for the first ones.
