This 12K (12,000) grit Naniwa Super Stone is an excellent Naniwa stone for superfine edges. I have used it on many razors and it further refines the already excellent results produced by the 10k stone as part of a progression. Equally, it is an excellent choice on its own to refresh the edge of a carbon steel razor which has just gone beyond the ability of a strop. A stand is available separately.
This is the same honing stone as the Naniwa Speciality Stone IE060008 – which has now been discontinued – but in different packaging and sold under a different name.
