I have recently obtained the Chosera 5k and 10k, I have been using the 1k for awhile to set bevels. I honed 6 razors this last weekend on the new stones. I really do not know what I am doing but I tried to experiment with spending more time on the 5k on a few razors and more time on the 10k with the rest to see what works. Out of the 6 that I honed 2 of them turned out to be fantastic and the others were not terrible but they need more work. The two that turned out great were 1/4 grind razors and the rest were full hollow. I was wondering if anyone could explain to me how to I know when I am finished with the 5k stone. I imagine I will figure it out with time but if someone has experience with these stones I would like to hear other experiences. I also got a DMT 325. I certainly am glad I did.
