I have a Mk1, Mk1 Mini, Mk3 and a Mk4 and I carry one of the three folders everyday. Typically I carry my Mk1 Mini as my EDC knife around town and at work saving the full size Mk1 as my field knife and the Mk4 as my "dress clothes" knife.
I have done some pretty mean things to all my RSKs (besides the Mk4... it is just too pretty to beat on) including things you shouldn't use a knife for (like prying and popping doors) and have yet to have a problem with them. Besides some specialty knives (Gerber Hinderer and Bladetech Responder) and multi-tools Doug's knifes are all that I carry.
Are they worth the money, absolutely! As with any tool you get what you pay for, with the Mk1 I think you get more then what you pay for, a S30V blade that stays sharp, a lightweight but stiff handle along with a rock solid locking system. Considering how often I see cheaper knifes broken by the user and thus needing replacement... in the end buy one RSK will probably cost less money in theend.
