In praise of the Guangxi stone
In my wetshaving journey I have abandoned many tools, then gone back to discover it was not the tool but the hand it was in that was insufficient. This applies to Feather blades, MWF, Gems, and a host of other items. Fortunately, I'm a packrat and rarely bin or sell anything, even when I'm not satisfied with it.
So it was with this stone. I had pretty much stopped using it. As I grew more and more fond of coticules, I came to agree with Bart that a perfectly good edge could be attained just by finishing with one and water. And I still believe that is true.
So now I have about 25 razors in random rotation. Some are superb. Some are perfectly fine, but require a little more work and care to get the perfect shave -- just enough to make it a less enjoyable experience.
Fortunately, I keep a honing journal. I went back to look at how I had finished each razor. Almost invariably, the best ones had been finished on the (rarely used) Chinese stone.
I'm going to go through the rotation and refinish the "good enough" blades. I'll post the results here -- it may take a few weeks.
I just ordered a couple of Nakayamas from O_S. I'm still looking forward to using them. Maybe something even better awaits. But, I think if there are still straight users around 100 years down the road, and assuming the Guangxi mine has played out by then, I wouldn't be at all surprised if O_S IV is selling the Japanese and the Chinese stones for around the same price.
