Help Identifying tool please

This was found in a co worker's grandfather's tool box. Any ideas? Thanks in advance.

It's a balancer for lawn mower blades.
Place the hole of the blade on the balancer, then measure (or eyeball) which side of the blade is lower. That's the side that needs more material removed. Repeat until the blade sits level.

Correct. I find I can get by with just holding a screw driver horizontally with the blade in the hole.

That works, to an extent, as does a nail stuck into the side of a bench.

But because of the sliding friction in the hole, you can end up being misled that way. The real balancer guarantees that the pivoting point is in the center. It's a little more accurate, though how much accuracy is required in balancing mower blades is debatable.

For my part, I use the plastic version of that balancer. It works for me, only cost a couple of bucks, and fits easily in my sharpening supplies drawer.

I've found a cone top and always wondered why it was stepped and casted so thin
