Pros: easy to use, wears slowly, excellent value
Cons: an oilstone so it can get messy
A basic oil stone for knife maintenance. I use the coarse side for setting initial bevels and repairing blade damage. The coarse side is P150 and is grey I use the fine side to finish the edge. the fine side is P400 and is orange I own one IB8 and four of the six inch IB6. I went to an 8" stone as it is easier to use for larger (over 6") blades.
These are oil stones and work best when there is a thin film of oil on the stone. I use food grade mineral oil and in a pinch have used vegetable cooking oil. Oil seems to do the best job of keeping swarf(the steel you have removed from the blade) in suspension. Norton India stones use aluminum oxide abrasive and work well for all types of knives. the India stones do not make a slurry commonly seen with Japanese water stones, where the first part of sharpening is making a slurry. They wear very slowly. After time, the stone will seem to be finer, as the abrasive has started to break down. I resurface at this point. I use a slurry of extra coarse (40 grit) silicon carbide and oil on a flat piece of steel. work the stone in the slurry until the entire surface has been scrubbed. clean off slurry then scrub the stone with mineral spirits or hot soap and water.
I use this stone in a fixture or in a pinch I lay it on a damp towel on table or countertop. i do this so i can use both hands to hold and move the knife against the stone. One of the issues when using this stone is there is no built in guide to maintain edge angle.
