Hello, I've been looking everywhere tried contacting Mel Pardue and even sent an email to Benchmade. All the images of 850's have micarta back spacers but the one I purchased online has a stainless steel back spacer, other than that the knife looks to be authentic. I was wondering if there are fake rainbow titaniums out there or if this could have been a change in build/design during 97-01 production. Any knowledge you could shed on this would be greatly appreciated.
