While I don't agree entirely with the OP's
actual statements I can sympathize with the
intent. The key factor is that most industrial designs are subjected to a dynamic not often faced in consumer goods--because they're purchased in bulk AND used as a professional tool, they need to be both economical AND high-performance, and as such it essentially forces extraneous features to be stripped away and the remaining variables adjusted in such a way that it's providing the absolute most functional performance possible for the price point. And that's something that a lot of designers could stand to pay a bit more attention to, at any price point.
I often see knives that are designed to sell, rather than designed to use. And some of them at prices that are so high you could buy a bevy of other more humble knives that would comfortably outfit you to tackle an impressive range of tasks with high efficiency. But, we all have different tastes, including where we place our weighted emphasis when considering a purchase. Some people place a lot of emphasis on the glam factor or having the latest and greatest materials despite the premium they carry. And that's fine! But as for me, my motto is that I always want my knives to be more fun to use than they are to buy, and so I put functional design elements first and foremost. The fact is, if you're trying to design down to a price point, simple steels with simple heat treatment protocols make good sense, because the geometry is the single most influential factor on performance and putting the scant dollars into that aspect means you may have to make the sacrifice of making a few other categories simply "good enough" because other features or processes may quickly ramp up the required machine hours and the price balloons just as quickly. There's an old saying that "any fool can make a thing that works, but it takes an engineer to make something that
barely works" and there's some truth in that that applies to that particular class of knives.
