HELP!!! I need help picking a unique boy name!?

I need help picking a boy name.. I like names that are unique and uncommon. I like names that remind me of a tough guy. My husband and I haven't found one that we both love but I like names such as dezil, taxes, knave, onyx however none of them have really meshed with us. Husband is a police officer and fire fighter he loves riding quad dirt bikes motorcycles trucks etc! I'd like a name that really resembles his dads hobbies and loves!
