This guy is all of 2 stop signs and 1 minute of driving from my house, with good pricing.
Stopped by and walked away with some interesting stuff this morning.
That big boy is a New Britain 15" adjustable, sweet !
A 3/8 USA Crafty ratchet, Allway saw handle, Lutz File and Tool Co CINT. O file/tool handle ( had a 6 sided tool in it),
another carbonium stone.
The wood handle driver set is from Perry-Fay Elyria. I like this one a lot !
Also a Williams, S-K and a Handy Hex wrench.
Nice way to start the day !!

Nice lot! What would one use a carbonium stone for?
I think Carborundum is a Trade Name. Generic = silicon carbide. Handy for axe blade dressing, for one.
You need carbonium stones to ask $275 for a set of Proto line wrenches after listing them for $75 :)
Carborundum is generic, actually. The green handled number in the photo was a kitchen tool for sharpening knives.
>Carborundum is generic, actually
In 1929 the Corborundum Company would have disagreed with you , it was a registered mark.
Like asprin , however, it has come into such general usage over time that it can no longer be protected as a trade mark...
If the green tool still has it's paper decal, it should have a circular mark with corborundum company written around the outside edge...
(I hardly ever find them with the decal still on them tho)
Branson is correct in Kitchen tool, I have seen them id'd as scythe sharpening tools, they are too short, you would cut off half your fingers sharpening a scythe with that thing;P
I believe one of my first posts on this forum was asking about a pair of these stones, back pre crash.
And I think were described as scythe sharpening stones...
This new one (far right) has more of a label than the others, also has CARBORUNDUM on the ferrule which the others dont.

The trade name "Carborundum" is from the element corundum which is at 9,0 on the hardness scale and eveyone above who mentioned sharpening stone is correct. Corundum is a naturally occuring aliminum oxide and is very hard. The stones and wheels came in a variety of sizes and were/are VERY effective.
Lots of info online here's a littl of it http://www.mineralszone.com/minerals/corundum.html
A little more information -- corundum, just as Ietech wrote, is a naturally occurring stone. We know corundum mostly in its forms as rubies and sapphires. Nine in hardness, on a scale of 1 to 10, with 10 being the hardness of diamonds. Nine in hardness translates as 90 Rockwell.

Scythe sharpening stones are quite different. Those I've seen are around 10 inches long and oval in cross section. No handles.
