Hey Ben...
I can't speak for anyone else, but I like "stuff." I think George Carlin did a bit some years ago on "stuff."
This current interest...is just that, an interest. My attention to khukuris initially and H.I. shortly after that was because I decided to investigate some "stuff" about woodswalking ala George Sears (Nessmuk). I found the forum. Just as the khuks are beautiful, simple, and represent an evolutionary answer to a practical need by a society, so too, some of the guns I have and are interested in are simple, practical, and represent an evolution of another sort.
The SKS was the arm of literally millions of East Bloc soldiers for many years. It is an evolutionary rifle. It doesn't break; doesn't require high maintenance, has inexpensive and widely-available ammunition, and is fun to shoot.
As Munk and other have said, it does not have the exclusive utility of being an anti-personel weapon, but may be used in hunting.
Again, speaking just for myself...my mauser-actioned scout rifle, my S&W revolver, my Winchester 97 shotgun, my Browning Buckmark .22 pistol, and the AYA sxs 20 guage shotgun are all varients of evolutionary design and utility, I like the sense of history and the knowledge that each represents. I like the beater single shot 20 and 12 guages as well.
I doubt that I fit in as a "gun nut," but maybe. I don't fanticize about heroism and conquest. Comes de revolution, I will stay home. But I like serviceable tools.
As for elegance?
Form follows function most often. These might be butt-ugly, but like any other rationalize bit of "stuff," I'm coming to find them interesting.
Also, I can't spend casual dollars, and have not been able to for almost a decade. This SKS seems to be the best buy on the marketplace for guns of this ilk.
Thanks for your interest.
