Hello folks guess it d be an interstin threa. We in Russia mostly recover old weapons shells, air bombs, or granades. Most of them are rusty beyond of state to cause hurt. But smtimes Germany made explosives are most dangerous. Cause some of their inner parts are made of stainless still, or are fit so tight and good that rust dont hurt inner space. So first thing we do when find an explosive is to define is it German made or Russian. freind of mine found a dagger it looked great. He was offered a good money for it but he refused to sell it. i told him not to keep it at home cause it might be a burrial item. So hi kept it in the trunk of his car. And in tree months he luckily died in a car eccident. Here is that dagger. And how it must have looked like.
