The issue you are speaking of is not just with knife manufacturers and china. The issue is related to business and is widespread. Most of the problem centers around trying to give customers more and more choices. Sellers are basically trying to find and offer the buyer the deciding point that will make them buy the product.
Take a look at a item like toothpaste. It wasn't that many years ago that if you needed a tube of toothpaste, you had 2 choices. Colgate or Crest.
Now you have 10-20 different kinds of Crest alone. Paste. Gel. Whitening. Flouride. Sensitive. Striped. Acid protection. Anti-gingivitis. And then you get the combinations, specially tailored depending on your exact needs. Older, Smoker, Kid, Young adult, the list goes on and on. All of it basically tailored to fool the customer into believing they are selecting exactly what they need, the perfect solution, just for them.
All of which leads to the next inevitability, discontinue the ones that don't sell, and try to come out with something that will. The emphasis becomes flooding the market with choices, instead of meeting the direct need. Manufacturers are essentially playing lotto, putting out a ton of choices, hoping that enough will click with the market and allow them to make profits. On the one hand, it is better to place a lot of small bets hoping to get winners rather than betting the farm on 1-2 products and dying if the big bets don't pay off....
I think this is a slightly different phenomenon than consumer products sold in retail stores. There, having more varieties is an attempt to crowd competitors out of literal shelf space. It’s rampant in snack chips and soda. Coke wants to take market share from Pepsi, they hope by releasing coke, Coke Zero, vanilla, lime, etc etc they will get more space and push Pepsi and other competitors out. But most retailers only have x amount of space and aren’t going to remove another brand. So as happened at a cafeteria where I worked, they would run out of the most popular item (Diet Pepsi) which only had 2 rows of bottles, meanwhile most everyone ignored the disgusting cherry, lime, and other gimmicks. The market plan risks cannibalizing their own brand and killing the golden goose but companies and marketers seem devoted to the technique.
