So I am wanting to get and new hone, something to to finish off of a Norton 4k/8k. Something I can also keep in the bathroom to quickly refresh a razor. People mention on this site that a barber hone is a great option for quick razor touch-ups in the bathroom. Would a naniwa 12K razor also be good for a quick touch-up in the bathroom since it does not need soaking? Or do these stone serve different purposes?
