Steel is CTS-XHP.
Its about a year and a half old. The nice thing about the Hinderers is it is stonewashed so it ages amazingly. I use it to score kydex, cut leather (I do a lot of leather work) and im also a project manager for a construction company. So for instance this morning I walked around a few new offices we built carving Xs into the walls to mark out where the electricians were going to mount all of there boxes. Its also my bottle opener. Beer caps dig in nice to the G10 so you can pop them out.
Im pretty reckless with my tools...
I like stonewashed finishes too, they hide scratches better, they also are decent as a rust resistant finish, i also like how it looks.
I have never seen or used a Hinderer in person but the fame is well deserved as your knife is in great condition for all the chores its doing, CTS-XHP must be really good at holding that edge however i was under the impression that since its usually hardened 61hrc or above that it would chip rather than roll, maybe i didnt interpret the pic correctly are those chips or rolled edge?
My edc knives do their chores diligently too, im sure i have to touch them up a lot more often than yours of course, for folders i carry a VG-10 Delica and a Boker Trance which is AUS-8, but the knife that i need touch up much less often is a fixed necker that i like to carry made by Jose Diaz, a Frog Leg in S30V hardened to 61-62 HRC, its a really great knife!, i promise to post pics soon.
