Information from the Spyderco product guide
From the 2008 product guide:
"First we made things sharp, then we made sharp things™ It might surprise people that Spyderco’s initial product was not a knife at all but a ceramic sharpening system. Our sharpening stones are AluminaCeramic, manufactured in the U.S. using a process combining a bonding agent with alumina particles (that are actually synthetic sapphires 15 to 25 microns in size). We shape them, then kiln fire them in temperatures exceeding 3000 degrees F (1649°C). On a Mohs hardness scale, Alumina Ceramic stones measure 9 (out of 10) and don’t require lubricants such as oil or water while using. The Mohs Scale of Mineral Hardness characterizes the scratch resistance of various minerals through the ability of a harder material to scratch a softer material. Talc: 1, Pure Gold: 3, Hardened Steel: 7, Spyderco sharpening stones: 9, Diamond: 10. Medium grit brown stones are open-cell stones (friable) and will wear out over time and repeated use. Their abrasive quality is ideal for removing steel stock or for dull blade and edges requiring re-profiling. Our white fine and ultra-fine grit stones are closed-cell ceramic and won’t wear with usage or time. They’re less abrasive, excelling at polishing and professionally finishing an edge. With any ceramic or glass implement, they will break or chip if dropped or roughly handled. They’re temperature resistant and dishwasher and autoclave safe."
History, mentionings from the forums etc.
I've said this before. "The edge is a ghost". It's been around for 40,000 years and still we study it. It's technically a wedge, the "W" must be silent. Bringing two bevels together is the beginning. Then we study materials that can support as thin an edge as possible at the apex, Then we study abrasives that can bring those two bevels to as fine an edge as the materials can handle. Time and practice takes you up through the grades and one day you are a graduate "edge Junky". In English, that means nuts.
This is a good place to learn.
