Where I used to live in western Colorado was mining country, and most everyone in town with a interest in that topic would carry a miner’s pick-hammer with them in the trunk. It has a hammer face on one end, and a pick on the other. For if they saw a likely outcropping along the way and wanted to stop and take a sample . I used the pick side of my hammer quite a few times to chip away blocks of ice from my truck’s wheels, usually in the ski resort parking lot at the end of a day of skiing. The parking lot grader would shove snow against the wheels that would later in the day freeze into solid blocks of ice. hmmm … I think that pick is still in the truck somewhere, probably behind the seat, I’ll have to go out and look for it tomorrow!
