It may be more of a trivial point than practical, but the coated R.A.M. seems to have 14C28N, rather than 13C26 as on the satin model.
For those wondering why the change, Kershaw has been slowly switching from 13C26 to 14C28N as their flagship steel type. Kershaw and/or retail outlets haven't run out of 13C26 quite yet, so only new models are readily available in 14C28N.
14C28N is slightly more wear resistant and corrosion resistant (all around very nice steel).
