I was just on the Straight razor designs site and was looking at the naniwa super stones and noticed that they didn't have a base mount. That's one of the things I liked about them. the ease of use. I'm getting ready to get a 5K stone but would like one with the plastic base. Are they no longer available. I also have a 325 diamond lapping plate and even though its only 1 year old I believe it's warn out. I don't hone for the public so I would have thought it would have lasted longer. I have the naniwa 1K 3/8K and the 12K so the 5K would be added to the mix. I still finish with the 20K sehiro. Is the place to order a wooden box for the naniwa stones. I haven't called SRD yet still kicking around the idea.
