jkatzman... rock on...trying new things is the fun in honing!!! When you play and learn and discover...in my opinion...it's the most fun!
When you get a stone thats so damn hard that even a worn dmt doesn't raise much of a slurry on it and your hardest nagura produces minimal slurry (which i appreciate nowadays) as that minimal amount of slurry breaks down and the steel is being removed at such a fine level,,, your slurry will oxidize (slowly turn to rust) and a whole new world of fine edges is at your doorstep!!! I'm sure i'm not the only one that has ever experienced this! Have fun my friend and using a dmt is ok in my books...bad honing habits well...
