Been honing since 2012 using synthetic stones. Finally five months ago bought my first jnat, an Ozuku Asagi, followed up soon by a Wakasa then a Shobu Asagi Tamamoku. I don't have any nagura, but my method is to use synthetic stones to 8k level then Atoma 1200 slurry and use one of the Japanese natural stones to finish with. (all three stones are hard, and fine particle size). Now, I've enjoyed reasonably good results with the Ozuku and a medium slurry diluted to a misty one with barely any pressure. My question is, that having done this technique with all three stones, the results are significantly better with the Shobu. I mean a markedly sharper smoother result. I have done basically the same things with the Ozuku and Wakasa, but I'm a little off the pace compared to the Shobu. So, is there a tweak I can try that might improve my results on the ozuku and Wakasa. If nagura is worth investing in, well, I'd try it, but at present I am enjoying the Shobu with DN. (there are photos of the hones in the Hones section). I would like to hear some opinions/options?
