At the risk of another well-deserved scolding PM from knarfeng

... as a "professional" Quality Engineer I can say without any fear of contradicting myself that "you get what you pay for".
True product quality is a delicate balance of design, materials, and manufacturing capability. Product cost (and margin) is a series of compromises in materials costs and manufacturing capability to reach a price point that meets a consumer need via a desirable combination of price, workmanship, and materials. In the real world it's possible to have a really well-made folding knife with attractive covers and mediocre metals that meets many consumer's expectations (cost versus quality). The KnifeNut (and I'm one) lives by an entirely different set of expectations than the "typical" knife buyer - we want what we want - and we all seem to want different mixes of price, quality, and pattern variety.
QC in a factory is going to fall into two very broad categories - and you
will pay for the diffence between the two. The less capable the manufacuring processes (too complex a topic for this thread) the more likely "product quality" is going to be inspected into the product via visual inspection. This make the QC process entirely subjective (a fact of the manufacturing world). Set the criteria too low and junk
escapes (QC lingo) ... set the criteria too high and you end up with "scrap" finished goods that kill the company's bottom line. The second strategy is to spend the resources to improve processes to the point that detailed visual inspection is not necessary (and even then you will have an occasional escape).
A frequent complaint on this forum is the inconsistent grind on (North American) high end production knives such as GEC and Queen (and most of the others also). Since these companies often tout their use of vintage equipment and the manual griding process is one of the last manufacturing steps, it's easy to understand why they don't risk the potential sale of an item by "over grinding" and turning a knife into scrap after the majority of the company's cost has been invested in it. Too much risk when the market is not willing to absorb the scrap costs which would be passed on to the customer.
I'd rather have a "new" dull high carbon knife (that I will sharpen anyway) made in America of quality materials than an out-of-the-box razor sharp stainless knife made somewhere else. Why? Because I'm a KnifeNut! Some other KnifeNut will see this completely opposite and I'm OK with that. Embrace your KnifeNuttiness and understand that to us the emphasis is on the "Knife" but to the rest of the world it's the "Nut" portion of our syndrome that seems most apparent.
From a metallurgical standpoint I'm not certain that a high carbon blade could tolerate the automated grinding processes used on stainless metals to achieve the near perfect grinds that many of these "foreign" knives have (like a disposable hobby knife blade). I want "patina" so stainless is always less appealing to me. Why you ask? Because I'm a KnifeNut!
