knuckle duster Low-poly 3D model

Knuckle Duster a knife and brass knuckles combination great for trench warafare, close combat, or just messing someone up in a bar, you decide.

I made this in Solidworks and I'm looking for feedback on how to make these models easier to use and how I can improve them to better suit what you need them to do. Please contact me or leave a comment if you have requests and advice
