Photos Sharpening stone I presume..Anyone ever seen one of these

Says carborundum which I looked up, is an abrasive.
I’ve never seen a setup like this.

I've seen those stones before. It's old. The company has been bought some time ago. Those were used for brush cutters, shears, lawn mower blades... A good find. DM

Yep...looks like a scythe stone or similar.

I had this hanging in my kitchen for years as decoration.
We're doing a little downsizing but decided to keep this piece along with a couple of steels.

Yes, for yard tools I think. I seem to recall seeing these in mail-order catalogs, marketed to those ends for gardeners & landscapers. Should be handy for a lot of uses.

'Carborundum' is the proprietary name given to silicon carbide ('SiC') abrasives, by the original inventor/discoverer of SiC.

It's a household sharpening stone mostly intended for use on common kitchen knives and the like. I can't turn up a Carborundum catalog scan the contains it but all the major abrasives companies made one at one point, and here it is in a Pike/Behr-Manning publication.
