I re-read your post and realized you asked other questions too.
Benchmade has been making knives since at least the early 90's, if not earlier. They run 4 lines: Gold, Black, Blue, and Red. They are a premier knifemaker based in Oregon.
The Gold class is usually a small number of their Black or Blue class knives that they've hyped up with super-nice steels and design improvements. U.S. made, high-dollar.
The Blue and Black class are their bread and butter. Their high-quality folders, fixed blades, and rescue gear with the latest steels and scale material. The Black class, generally speaking, is their law enforcement and "ninja" type line, for lack of a better term, though I'd hesitate to put any Benchmade knife into the "mall ninja" category. The Nimravus (BM140) is a Black Class knife. Black and Blue Class are U.S. made.
Their Red Class knives are made overseas - Taiwan, China, and elsewhere - and are priced to compete with the other sell-outs who've gone overseas. The designs aren;t bad, the steels used are not terrible, and the scale material of the ones I've handled compares with other name-brand manufacturers. I refuse to buy Red Class for other reasons, mainly because I think BM should keep their entire line here. If they want to compete with the swap meet knife manufacturers, then just give up on quality and do their entire line overseas. Then I can buy from some other knifemaker and not worry about greed and integrity issues.
Benchmade, generally speaking, doesn;t come out each year with the boldest and most daring designs, (to their fault according to some Forum members). I, for one, care not for the newest and flashiest "low-rider" knife, I'm more reserved and want quality over flash. That said, BM has made several or more knives that other manufacturers have probably based their flashy designs on.
Overall, BM is, in my book, one of the most respected of the premier assembly-line makers out there. I have several and they are indeed of the highest quality. Their Customer Service, while sometimes slow, is second to none (or at least to very few).
