A Dussack (also dusack, dysack, tesak, tuseckn, thuseckn, disackn, or dusägge, dusegge, dusegg, from the Czech "tesák") is a large type of knife often with a long cutting edge in the front and a shorter in the back. It is thought to originate from Central and Eastern Europe (specifically in Bohemia in 300 AD). No wooden (or leather) practice dussacks are known to have survived; unsurprising given the perishable nature of the dussack, and only woodcuts and training manuals from the period document their existence.
