You're looking at a US 1918 Mark 1 Brass Knuckle Knife, also known as a "Trench Knife". This knife has three attack modes: striking an opponent with the pommel nut, punching them with the brass knuckle, and stabbing them with the blade. The textures are perfect for recreating the weathered brass and metal pommel/blade. The Zip file contains the Max file, along with the 2048 Diffuse, Spec, Gloss, and ZBrush generated normal maps. The model's geometry has been optimized to quads and tri's only.
A great mesh to use as a melee weapon or accessory to a character model! Had a lot of fun making this, so I hope you'll have a lot of fun using it!
