Another advantage of the Benchmade range is the 'Lifesharp' guarantee - basically if it starts to get blunt you can send it back (covering postage) to benchmade and they'll resharpen it for you.
Which I need to find the info on. I got a switchblade from 5 years ago that's getting dull.
are you active military/law enforcement? I'm assuming you have the use of both arms :) if you dont meet the federal guidelines and are registered with them they will not send it back to you. You can however have a Benchmade dealer send it in for you to be serviced. If you don't have one local I'll be happy to help you out.
