Popular in the 13th Century, the Bollock Dagger was known for it's distinctive shape. With twin rounded metal swelling for hand guards, the weapon had some resemblance to male testicles (hence the English name Bollock). The guard was made of common wood with a simple "washer-type" attachment for a blade and handle break (made of metal). Similar in design to a Dirk, it was a popular personal weapon (and no doubt saw close quarters use on a battlefield or two). Popular in England, Scotland and Wales. The blade was 8 to 12 inches in length. During The Victorian Era, the Bollocks name was changed to "The Kidney" (to remove any sexual allusions).
