I decided to take a trip to the flea market yesterday and picked up this carborundum sharpening stone for 2 dollars. I hope that wasn't to much because the box has $1.25 marked on it.

The knives pictured with it were sharpened this morning with it. It really worked well especially on the cv trapper.

God Bless

Carborundum is silicon carbide. It comes under many names. Norton likes to call theirs "Crystolon". It's a good abrasive for the early/intermediate stages of sharpening imho.
Aluminum oxide (India), Arkansas stones (Washita etc) and ceramics are better for "finishing" depending on the preferred grit.

How wrong can you go for $2 ;)
 
Carborundum cuts pretty fast, but it also wears pretty fast. That's a new (well I guess that's a relative term) stone and well worth what you paid for it; maybe "unused" is a better term.

I used to use a pretty coarse carborundum stone to work my edge down on a really dull edge before swapping to a Norton India stone and strop to finish. Use my newer diamond hones nowadays.

That picture brings up memories of those old dished Carborundum stones found in every kitchen drawer in my extended family while growing up. They led to every butcher and carving knife to develop a characteristic recurve over the years
 
I usually finish with a glass smooth arkansas stone and strop on leather. This was just something different from the old standards.
This stone looked to be used once on the course side of the stone and unused on the smooth side.

What I like are the old Arkansas stones that folks happen upon every now and again.

Ray Kirk (the master smith) once sent me an old stone that he had come upon at someone's yard sale in rural Oklahoma. He told me the old woman that sold it to him said it had belonged to a very old gentleman that would sit for hours outdoors touching up his blades with that stone. (He had since passed away.)

Every time I'd use the stone I'd feel a sense of communion with the past.

I hope your carborundum stone helps you feel the same kind of connection to those who came before. Good stuff.
