What is this, I know!

[Graysonhogs]

Had to google it.

[Hills of Texas]

Old blade strop

[Gunnyart]

spring loaded rotary strop?

[lovemylegacy]

I would assume its a Razor blade strop. After all it does say "strop". I guess it took the place of leather strops?

Hills of Texas, winner winner, chicken dinner. Sharpened double edged blades.

[Gunnyart]

Not spring loaded, maybe the knurled edge is to drive it across a surface?

Where paper clip is turns the dic, I will try to bet a working pic.

Had me!!!!! no idea

[Leon County Slayer]

Razor sharpener I’m guessing by what it says on the device.

Those things are wonders of engineering. If you crank the handle, it will flop the blade over on every other revolution.
