Thread: Does anyone recognize this hone?

Back in the seventies when I was a kid my dad bought a sharpening business. It was primarily for saws, belsaw machines, a carbide sharpener etc but one of the things included in it was this hone which is in a cheese box. It's 10 3/4" long, 3 3/4" across the face and 3 1/4" tall. you'll kindly have to pardon my illiteracy about hones. I'm assuming, I think correctly, that the sides, which are bluish in color (2nd picture), are not actually sharpening surfaces just a substrate. He told my brother and I at the time not to use that to sharpen knives or other blades because it was made for sharpening razors but I never really knew anything beyond what he said.





Again pardon my ignorance but it appears to be the same on both cutting surfaces but I'm not certain. I'm assuming, based on the little I know about stones and it's age, that it's probably an oil stone. I'm also assuming that it's a man-made stone because of the fact that it seems like it has a different substrate in the middle than on the top and bottom side plus it looks somewhat like poured concrete. Any help with information on it would be appreciated. Thanks in advance for any help.

I cant help but i love looking at old stones. That thing looks like a concrete brick! I will be watching to see what it is.

Me too! Watching!

I would take a shaving razor and give it a whirl. See what it does. Compare scratch patterns with known grit stones and try to get an idea what it may be capable of doing.

I've actually run a razor across it some. I don't have a microscope or even a jeweler's glass to see it up close but it left the edge rather shiny like it looks after the pyramid progression or after the 12k stone. Again, I am quite new to honing and only really know how to follow directions from what I've read.

paul scrub it maybe, soak it with some simple green so we can see its true colors....

it will prolly need some lapping to get to really sing

....now i have hone envy

it looks like it is a white-ish hone.... which might it narrow down
