Hard use can be a function of quality construction and/or knife design, including blade geometry. Hard use is different from abuse.
The Military is a very well constructed, high-quality knife, so in that regard it will easily handle hard use within reason.
However, the Military is designed primarily for high-performance cutting rather than for its ability to withstand abuse. I love the pointy point and that thin, flat grind because those design features let the knife do typical knife tasks at a higher level of performance than the typical knife.
I also love the large blade and the thin handle, which gives me the leverage of a large blade in a package that is easy to carry.
My own sense is that people who want a super hard-use knife are either using the wrong tool or are awaiting the demise of civilization or just like the idea of carrying a knife that is nearly impossible to destroy. Those people are willing to give up high-performance cutting in favor of those other values.
