Let's see those sharpeners!

Oh, I didn't notice it. I'm on a smart phone. I imagine most of you are on a computer. It was auto correct.
 
I've got a bear brand Norton India im9 fine stone, it's really big to. I've never used an India. How is it compared to Arkansas and the sic?

My next project is making a tilting holder for the Norton Tri-hone. It will be mounted on an Aluminum slab held in a tilt vise. The upended Tri-hone will be run dry. A horizontal Tri-hone will be used to bathe and clean the triangular prisms. This will definitely be a bench tool, but It will solve a lot of problems.
 
Here is a photo of a Norton IB8 stone with the bear emblem on it. This stone is a mid 80's combination coarse / fine India bench stone. Hence, IB8= India Bench 8. When Norton's mfg. went outside the USA the bear emblem was dropped. Sometime around the late 90's. DM

This is what I have, it was loaded up with slurry when I got it. I cleaned up, but it was extremely hard to do. Its about 14 in long inch thick and 4 in wide.
 
A man made stone will cut most any steel much faster than a natural stone. As their hardness are much higher. Not just this but their grits and binders are different. A Arkansas stone has a grain like a cobblestone street. Whereas the India and SiC stones grains have points like grains of sand. This enhances cutting. The India being ceramic and it's grains don't slough off during grinding like SiC. Which is considered a water stone. The SiC grains during grinding will slough off creating new material but wears away more quickly than a India. The India is a good stone and high enough level of grit to take a blade. Give it some stropping on slurry and you'll have a very sharp edge with good bite and retention. DM
 
Give 'the blade' some stropping on a leather strop with slurry applied, in order to clean it up, remove the burr and refine it further. Coming off this stone; this makes for a very sharp blade. DM
 
Here you go. Read further in this; http://en.wikipedia.org/wiki/Aluminium_oxide
You won't get much slurry off a India stone.
Purchase a slurry in 300-400 grit range from Home Depot and outlets you'll find on this forum. Ace Hardware stores even carries some. Google Flex-cut Gold. Apply this to your leather strop using a carrier of mineral oil. Rub it in and your ready to use it after grinding it (the blade) on your India stone. DM
 
Your India stone in that size must have been some sort of specialty stone. Not for the IM-313, as that has not changed in size from way back (1950) or before. Perhaps your stone was for a different model. As I've not seen one that size in any meat market I inspect in our state and much of Texas as well. DM

The remains of sharpening material left on a stone is called swarf. This should be removed. Good. Next time try using lacquer thinner (outdoors)(wetting the stone with it ) and a wire brush with elbow grease. Then wipe with a cloth. It comes right off. It sounds like the previous user may have used it dry. Use mineral oil on it. DM

Alrighty I'll try that, and yea whoever had it before me did I believe. It took over a hour to get it cleaned up to where it would bite again.
 
Yes, sounds like they did. Comet with H2o and a wire brush also makes a good stone cleaner. DM
