Ballock Knife

An item at Metropolitan Museum of Art

The ballock knife, also referred to as a kidney dagger, was widely used in the later Middle Ages, in both civilian and military contexts. In Talhoffer's Fechtbuch it is shown in use by armored combatants to deliver a coup de grâce, and in the section devoted to unarmored knife fighting.

Arms and Armor

An exhibit at Metropolitan Museum of Art

The principal goals of the Arms and Armor Department are to collect, preserve, research, publish, and exhibit distinguished examples representing the art of the armorer, swordsmith, and gunmaker. Arms and armor have been a vital part of virtually all cultures for thousands of years, pivotal not only in conquest and defense, but also in court pageantry and ceremonial events. Throughout time the best armor and weapons have represented the highest artistic and technical capabilities of the society and period in which they were made, forming a unique aspect of both art history and material culture.
