Thread: Naniwa Chosera and Super Stone opinions, please

Bart has said good things about the Chosera 10K (very sharp edges, good feedback), but he then finished on a hard coticule for smoothness. I think he has the 5K as well.

My experience w/ the supers was that they needed to be lapped frequently as well, not because they dished easily, but because they tended to swell/shrink w/ moisture. After every use, they would need a quick lapping or they wouldn't be totally flat the next time I got them wet. They were fast cutters & could give a nice edge, but they gave me no feedback on how the edge was developing. (They gave a very clear feeling on where the edge was on the stone, which was nice, but not how far from "done" it was.) They certainly did the job and were pretty consistent, but I prefer my coticule doing Bart's "Dilucot" method. Just personal preference here. As always, YMMV.
