Developed in the late 15th Century, The Koncerz was similar to the English Estoc (or Tuck Sword). Made for the Polish Hussar (or Light Cavalry), the weapon was unusual for not only NOT being curved (as a traditional cavalry blade) - but it had no blade edge!. The blade tip was sharpened only. The purpose of the blade was to stab and thrust (not cut and slash). Additionally, the blade tip was rectangular shaped. The blade was long at 45 to 48 inches in length. This served the cavalryman well for attacking from horseback (downward to ground troops). It also featured a standard "D' guard wrist and hand protector. They were made of steel and brass.
