Going to take Cliff's advice and get an inexpensive 220 SiC stone instead of a fancy diamond one for quick reprofiling. Can't find any online though. Anyone know where to get 'em?
 
Forget on line you go to sears and get one there. You can also check any hardware store and should find one.
 
You may be able to find the Norton Crystolon stones locally. From the Norton mfg blurb: "Crystolon stones are made of silicon carbide electric-furnace abrasive, gray or black in color."

Home Depot lists them on their website for $12. I've likewise seen this type of stone at hardware stores.

There is a *huge* difference between an India SiC stone and the japanese 220 grit SiC waterstone, it is like comparing walking to driving a car. Lee Valley sells the SiC waterstone, most places selling waterstones carry them.

So what is your point? Are you saying you cann't get a black coarse silicon carbide bench stone at Sears or a hardware store?
 
Yes you can however the cutting speed is *SLOW* compared to the SiC waterstone Lee Valley sells.

Cliff, silly question, but do you use the 220 SiC waterstone per instructions? That is, soak it and keep watering it, etc.?
 
WOW!!! I wouldn't even want a stone that cuts alot faster than the coarse SiC hone I got from Sears. About 30 strokes and thats all it takes to regrind just about any angle you want on a blade. Hard for me to imagen grinding faster.

I took the large block, cut it up into pieces with a handsaw and use them like files to reset edges, on a small folder, you can take the edge from 25 to 10 in a couple of minutes. Keep the block wet, press very hard and go back and forth really fast. This isn't about being precise or acurate, you are just rough shaping.

Yes, that is it. It is a massive stone, just check the dimensions. Only 2/5 of my is left, yet that is still about four times the amount abrasive on the common SiC hones. The very first time you use it to adjust an edge angle you will regret not buying it sooner. It will also completely change your perspective on sharpening because machinability of a steel will mean nothing at all anymore.
