Here is the description.

"The knife gained notoriety in the former Yugoslavian countries because it was believed to be used by the Croatian Usta?e during World War II for the killing of prisoners in the concentration camps of the Nazi-puppet Independent State of Croatia, most notably the Jasenovac concentration camp. It is said that in the Jasenovac concentration camp competitions in speedy slaughter were organized by the Usta?e. The winner of one such competition, Petar Brzica slit the throats of 1,300 or 1360 prisoners."

Probably collectable but not by me.
