Benchmade's more expensive knives are all made in the USA. The ones made overseas are part of their Red Line and way cheaper than anything else they make. I wasn't even considering the Red Line in this thread.
Kershaw and Spyderco do offer some great values, but they both have their lines that are as much or more than Benchmade. Benchmade has always (up until now anyway) stayed with the higher end, $100 and up market.
Both Kershaw and Spyderco have their benefits. Kershaw has the best spring assist mechanism and one of the best designers around with Ken Onion. Spyderco has the popular opening hole and the excellent VG-10 as a base steel.
However, as a whole, I find I prefer Benchmade. They use great materials, great fit and finish, and have a great warranty. They are worth what they retail for if you ask me. It is something you shouldn't ever be replacing, unless you are really abusive. Collectors are a whole different ballgame, and I don't think Benchmade is focusing on the collectors.
