Choppa

Choppas are a general term given to any ork close combat weapon, typically heavy swords and axes. Slugga Boyz are always armed with a slugga and choppa, at least until they save up enough teef to buy something better, like a shoota

There's little finess to a choppa, most are little more than sharpened pieces of scrap metal which have been roughly shaped into something resembling a sword or axe. There are, however, more advanced choppas, often taking the form of a crude chainsword.
