Why pick on Buck? Why not Case, Kershaw, Spyderco, or any other U.S. based manufacturer, who all have iconic designs?
Buck is primarily a hunting knife maker. Their bread and butter is making affordable, decent knives for folks that shop at big box stores. They make a few knives that we traditional knife enthusiasts at BF appreciate, but we constitute a small faction of their customers. They use modern materials and designs to have broad appeal, seemingly taking the "shotgun" approach, meaning they roll out various incarnations of a single concept, and wait to see which one stands the test of time, while unpopular models are discontinued. It's a strategy that seems to have served them well; people like trying out new models from a company they like, and it doesn't break the bank for them to do so. In conclusion, the last thing they will be is a company that focuses solely on perfecting a handful of products.
