What are you going to be using the pick for? turning over rocks or breaking them? screwdrivers are usually magnetized, same with hammers. you could get a rock pick/hammer and superglue a strong earth magnet to the hammer part. I'm sure there are specialized tools meteorite enthusiasts use or just make themselves. If I were you I would look up what rock hammer the "Meteorite Men" use on their show. It's magnetic and can be used to flip or break rocks
