The Ork Choppa is the default melee weapon of Orks.

The weapon, like all of Ork craft, is of crude design. It consists of a blade of some sort, sharpened by stone as opposed to being intricately smithed. The end product is a weapon that mimics an axe or a large knife.

In Dark Millennium Online Edit

Orks have been seen wielding the weapon in the original game trailers.
