and no, i don't take the "all coticules are great, you just have to use them the right way" as gospel. i love these stones for their variety, each one is a surprise packet. but i think coticules are like most other natural stones, there are good ones and bad ones. of course i might be wrong. however, there hasn't been an edge finished on a not so brilliant coticule that i wasn't able to improve significantly on a nice japanese stone.
