I've had these around since I was a kid but just recently realized what it's used for.

What do you think it is and what is it used for?

*edit. @Lurker17 got it. It's a magnet that's forced down a cow's throat so that if they eat metal debris then the magnet keeps it in their stomach.

That's the Blackpill

Size and scale would help.

Great question. About the length and girth of an adult's index finger.

Is this tapered?

It's the pestle from a mortar and pestle set. You can use either end to pestle.

I learned something today.

I've played with these magnets since I was a young'n and I just realized what they were used for last week. You get them back after the cow is slaughtered.

That's pretty funny.

It is but knowing that we're facing having to deal with what led to such an invention is troubling.

Cow pill (magnetic) to pick up any iron nails the cow might ingest.

You win!

It's to "cure" "machine sickness".

Actually, I'd never seen one before, but knew of them. They sit in the bottom of the first stomach and hold any ingested iron there until it rusts to nothing, protecting the rest of the cow's digestive tract.

It's also just to keep the metal in place long enough for the cow to reach the age of slaughter. A few cents(then) to protect a food investment. They aren't pets. Hence where this was posted.

This is a cow magnet. These are magnets that can be shot into a cows stomach with a gun thing like a gigantic pill. It sits in their stomach and if they eat a piece of metal it sticks instead of traveling through the cow and potentially killing them. Source: I went to middle school with this dirty Mexican kid who's uncle worked in a cattle kill line. He would steal them. The kid would sell them for .25c. I still have one of them somewhere.

Exactly what it is but I don't think projectile insertion is necessary unless on a large scale farm but seems extreme even then.

Those are great for cleaning up the metal shavings off your drill press.

I go metal detecting in the desert a lot. Often we will find what we call cow bubble gum, pieces of chewed up aluminum. It’s kinda surprising how much of it there is out in the middle of nowhere. So you gotta think it had to of passed through the cow that far away from where a human would toss a can. You’d think the razor thickness of an aluminum can would fuk a cow’s stomach up more than the types of metal a cow might swallow.

They're great for a lot of things. Drop a screw? Got it! Is it steal? Nope! Can I get this to spin by doing x, y or z? You betcha!

Aluminum bubblegum though. That is interesting and how in the world does any sort of animal pass that without issue. Who of us hasn't seen a bid of a goat chewing up a beer can and asked "Wtf?".

Definitely a useful tool to keep around. I keep one stuck to the side of my forge to check if I’ve reached the Curry Point or non-magnetic when heat treating knives and tooling. Don’t know if it’s true or not, but some if not most of the new ones have neodymium magnets in just the ends, where the older ones were all magnetic. I’ve had mine for decades, they’re fully magnetic as far as I can tell.

My grandparents fed the dogs chicken bones and ribs all the time and they never had a problem. Heck grandma would crack rib bones with her teeth to get at the marrow and suck on them. She lived to 98. Sharp bits of metal, ferrous or non ferrous is another matter though!

magnetic stirrer?

It is not a stirrer but you could be positively or negatively on a right path.
