A Chinese man learned that the device he'd been using to crack walnuts for 25 years is, in fact, an old hand grenade. Alex Linder at Shanghaiist reports that he realized what it was after picking up a safety leaflet about explosives, then handed it in to the police.
Ran said that he received the "nutcracker" as a "gift" back in 1991, though he didn't say what kind "friend" had given him the device.
It's also not clear what Ran will use to crack open walnuts now.
