The title says it all,pretty much. I was experimenting with a 6000 grit water stone I had bought. First,I used my coarse,white and ultra fine white ceramic stones to produce an edge that would easily shave. Then,I tried a 6000 grit water stone I had bought. It lost the sharp edge I had gotten on my knife. I went back to the ultra fine Spyderco,and the shaving edge returned.
I'm not sure if the Spyderco is actually finer,or just harder,which causes it in effect to have a finer surface. But,the Spyderco will out sharpen the 6000 grit water stone. And,I haven't even gotten rid of the somewhat "toothed" feeling surface of the UF stone as cut at the factory. Ceramic stones being so hard,it will take some time to finally wear off the fine grinding marks on the surface of the UF stone.
I did take a few licks on my MDF with green LV compound on it,but only AFTER I had already gotten the shaving edge from just the stone.
OH NO!!!!!! I have just started ANOTHER sharpening thread!!!!!!
