Well, I told my wife I'm getting into str8 razor shaving to save money, YEAH RIGHT!!! On to the stones!

I think I've made the decision to purchase the Naniwa 12k super stone for touch ups and eventually be a part of a full line up.

Given this, I have a few questions about Naniwas. Has anyone used the Naniwa 3k/8k combo stone? Would the 3k/8k combo be the equivalent of the Norton 4k/8k combo? And is 3k to 8k a normal progression? Or should I be thinking of the 5k/8k/12k progression?

Thanks!
