Thread: Vintage Hone ID?

Austin,
If she is giving off oil in the water & she does favor an India /Carborundum in the photos; then she is Impregnated at the factory with that petroleum based lubricant (oil). It is not made to be "de-oiled", that oil is there to help keep the metal particles from filling the pores too fast & aid in the cutting.

EZ-Off would be o.k. for about 15 to 20 minutes only, to remove what is obviously years of , God knows what, lubricants on the stones surface.

Keep in mind that that stone is old & Ez-Off is hardcore, too muck time on it can start to effect the bonding of the grit.

Just my thoughts.

Here is my foray into India stones! It was as black as yours when I got it. Great for knives!

With out a doubt I know that is a India stone

Thanks for the additional opinions and input on this stone. The link provided by sharptonn sounds exactly like this one. Very hard stone, would eat my DMT 325. Water runs off it. Definitely has seen some oil but will hold off on the oven cleaner. The brown slurry I talked about initially was probably from my slurry stone not this stone! This doesn't generate slurry on its own. It does have those small orange spots. It is very old and both edges are relatively still flat but will probably try to lapp it somewhat. Fast cutter, a bevel setter, and chip remover. Since this was an entire lot of stones, believe this guy used this stone as the bevel setter as he had a long carborundum for mid work, and a old Franz Swaty and old Belgium coticule (Yellow/Cream & BBW) as his finishers.

He also had what I believe is a hard Arkansas that was dished on all sides that came in an old box made from poplar or white pine? Here are a few pics of that stone. It is really smooth and hard. Comments? Thanks for everyone's input on the India.

Another vote for the first one being an india stone. I have not bought most of my india stones on purpose, but I have accumulated them when I was buying a group of stones from a machinist or whatever. For some reason, the machinists LOVED india stones.

The different brands have binders that are all different colors and feels, some of them even feeling muddy and slick when slurried instead of gritty. but the first one doesn't have the characteristic look of a novaculite stone. The one you just posted does, though.

For me, a medium india scuffed by a diamond hone with the slurry left on top is my first stone if a razor is in really bad shape. It is coarse, will cut anything (since it's the same family of abrasives as a waterstone) and they stay super flat. Most of the india stones I get from machinists look like they have been used until they are loaded up and then cast aside, I guess because they decided the stones no longer cut.

Dave, thanks for this info. So, you think both of these hones are India stones? Did I get that right from your second paragraph?

I think the one at the beginning of the thread is some type of india stone, I think the one you just posted a couple of posts ago is a novaculite (natural arkansas) stone.

I'm not sure it's an India stone ... those are orange aren't they ... and aren't they dual hones? With a black side?

It could be a manmade oil made by norton.
i might have one that looks like that once had the indian markings still on it but
a gave it a good cleaning good stone for knives.

The first has orange specs on all sides. Not dual hones/combo. The second one is hard, and color is a butterscotch. May have some oil on it as well. Believe it is vintage as in well worn, Arkansas stone of some sort?
