Does anyone know what the steel really is with the CarboNext line? JCK's site is a bit vague, unless I just don't know what Honko steel corresponds to in standard nomenclature. Also, anyone use a CarboNext for a while? How rust/stain resistant is it? I assume it forms a patina like a carbon or no? Toying with a suji with this line. Also, anyone ever try out the VG-10 Kagayaki line? Their handles look amazing.
