I was amazed that you cannot use you hunting knife as a weapon, so the idea of more melee weapons like spiked bats and pipes is awesome And i think a good use for the crowbar is to use it for prying bits of metal (scrap metal for repairing you hull or sheet metal for armour) off wreaked vehicles and using the pieces to reinforce you car, not so much to stop bullets but to protect the engine from low level crashes into trees and such
