Meat Tenderizer
If you’re looking for weird objects in your home, the first place you should check is your kitchen drawers. There are probably 50 tools in there that you can’t name and that you’ve never seen your parents use before. Uploading images of them is a great way to get some posting karma.
This person did just that and found a weird mace-like weapon, which we’re fairly certain belongs nowhere near a kitchen. Someone informed the OP that it was a meat tenderizer, though it looks nothing like any meat tenderizer we’ve seen before. It could probably become a handy burglar deterrent if you’re brave enough.
