I would second the idea of getting either a villager or a blem. If the knife is going to be a hard-core 'user,' I would actually go with the villager.
Consider: a villager khuk is basically exactly how a kami would make it if it was going to be used in Nepal. I cannot imagine conditions more extreme than nepali use, unless you are either deliberately pushing the knife to its limit to see if it yields, or you live in a rain forest and trek to the top of snowcapped peaks on a regular basis.
If the fit and finish is suitable for hard nepali use, it is suitable for whatever treatment and care (or lack thereof) you will give it.
Also, you will not feel in the least bit bad about getting it banged up and dirty. The blade will already be ugly. The same cannot be said of a 'line' khuk or a 'blem.' I have yet to do anything but the most rudimentary and basic tasks with my Sirupati, for fear of getting a scratch on the beautiful polished swordlike blade...
