What kind of bones are these?

[Ankeeland97]

Found these in my yard a while back. Was wondering if anyone could tell me what those lines are in them and what kind of bones they are? The lines go all the way around them but not all the way through. I'm sure there's a simple explanation. But I have yet to find it.

Maybe they are cut marks from butchering process.

Kind of looks like they were bones in beef roast that were then run through a cutting process.
The leg bone really has uniform cuts. (spacing)
Never seen this before, and have dug a lot of bones up over the years.

I wonder about some type of mechanical de-boner. Possibly for cutting stew meat off of lower legs. It may be from rendering where nothing is wasted. A lot of pet food “meat” comes from scraps.

The bones could of been from the de-boner and then brought home for dog/soup bones.
The process was done by a measured mechanical cutter for sure.

I was thinking along the same lines.
For adding bone meal to the dog's food?

Or maybe it was a push "stick" for pushing meat into some kind of meat grinder?

I would think a push stick would end up with more of a taper to it. ?
