What are the pros & con's of the combo crystalon vs the combo India stone?
The Crystalon is silicon carbide, so grinds a bit faster and very consistent across steel types. It also breaks down a bit as it goes, generating a thin mud that inhibits burr formation a bit as it grinds, and constantly exposes fresh abrasive. This mud makes an excellent improvised stropping compound. Has very good to excellent tactile feedback.
The India stone is a durable aluminum oxide. It grinds a bit slower, but makes a cleaner finish than the SIC stones. As it breaks in it can create an edge much finer than its rated grit. Still has very good feedback. Is more susceptible to glazing or plugging, a SIC stone can be used dry from time to time, an India stone really shouldn't be used without oil and if it is should be scrubbed good afterward.
They both work best with oil IMHO. Both are great all purpose stones. I find the Crystalon to be more user friendly, but both stones are among my favorites.
