I think that a lot of people that frequent this forum and others like it get a false impression of knives as far as "fit and finish", and expect near perfection for a knife that they pay <$50 for. Buck has been around for a lot of years, and like most if not all companies, face fierce competition. To produce the large quantity of knives required to keep up with demand, their qc will suffer. Manufacturing costs have risen sharply, due to increase in labor, material cost, packaging, shipping, etc, etc. If you compare what they charge for their products today, verses what they charged say15 years ago, there is not a large increase in their prices. Their knives are made for the working man and designed to be used for a multitude of tasks. They are not necessarily produced for the fancy high quality collector.
Given their "forever" warranty and customer service reputation, I think you get a good value for your money spent when buying their products. Yes, you will get a bad sample from time to time, but they will stand behind it if you send it in for repair/replacement. Complaining about it on a public forum before trying to get it worked out with their customer service will never get it fixed for you. If you can not get satisfaction after sending it back, then make your case on a public forum with all the particulars included in your post. There is usually two sides to every story, and we only get to hear one of them here.
