Do you really believe that some of the more function oriented companies would rather grind their knife a certain way than to just flip the knife over for the picture?
Yes!
Think of the private/public sides of knives. Most people are righties, so you look at the LEFT side of the knife while you cut. Who wants to look at some flat, featurless side when you can stare at a nice hollow grind ow some neat-o serrations. Put a right ground knife and a left ground knife on a table and have 100 knife users walk by, and I'll bet what little cahs I have that most will pickup and stare longer at the knife that is ground on the left side. A knife user who wants 100% utility, which doesn't include aesthetic appreciation, isn't going to pic this knife up. But most of us do care about these aesthetic issues. Just look at the people who get a scratch on their knife from sharpening and their world comes to an end!
Forumite samhell made an interesting observation as well that I suspect bears some weight. Having ground out a few knives myself, and being a righty, I can tell you that grinding chisel ground knives with the grind on the left side is easier for righties than grinding them on the right side. So, Righties need grinds on the right side, but righties grind bevels on the left side easier than on the right side. Sure knife makers train their hands to be much more ambidexterous, but this does take a while to do. I wouldn'tbe surprised if many moons ago Mr. Emerson made 2 blanks for the famous CQC-6 model, ground one on the left side, and one on the right, and made a quick decision about which was easier to produce. Just to clarify, I haven't inquired about this at all, but this question arose from 2 hobby makers chatting one day.
Also, you have to be careful about what you mean when you say the knife is ground on the "wrong" side. For utility work that involves cutting away from yourself, righties want bevels on the right side. For work that involves cutting toward yourself, righties want left bevels. So actually, for fighters a knife ground on the left side is probably best, as inside slashes are much more natural and powerful to do than outside slashes! And for stabs, it probably doesn't matter too much if the bevel is on the right or left. So any knife user could actually have uses for right and left beveled knives, depending on the work they do.
