Hello...I can do a decent job honing a razor but believe there is always room for improvement. My current set up is a flight of Naniwa Super Stones 1k, 5k, 8k, 12k. I also have a coticule, BBW, and chunk of Welsh slate which I am continuing to learn. Must say I get more consistent results (and more easily) from the Naniwas.

Recently I stumbled upon a fair deal for a Shapton 3k Glass Stone. Question being..would this be worth acquiring and fitting into the progression of the Naniwa SS scheme, or would it be redundant??

Thanks..........
