The only way they could do any damage whatsoever, is MAYBE if you kept them in the same spot on your person every day for years (such as, say, on a keyring), and even THEN only maybe a mild rash over time and maybe a .1% increase in the risk of a few types of cancers, and even then, that's unlikely. It's not more radioactive than your cell phone. The only plausible, and even then highly unlikely, way that it could "fucking kill you" is if there was some kind of manufacturing mistake and the uranium used in it was not properly depleted, and so was much more radioactive than spec.
Back in the 40s and 50s, researchers used to handle cores of plutonium and uranium with their bare hands wearing nothing more than gloves, lab coats, and safety goggles. They subsequently instituted strict safety standards more to prevent fatalities from accidents - such as prompt criticality incidents, which killed a few nuclear fission pioneers - and illnesses from long-term daily exposure. And this was with freaking fissile material, not DU.
