I visited Benchmade yesterday to drop of a knife for a spa treatment, and took along a balisong I've had in my drawer for over 10 years. It didn't have a model number on it and I had no idea what it was other than a Benchmade. The folks in warranty repair confirmed it is a Benchmade model 42 with a t-latch (and not a counterfeit). They had to look up when this model/configuration was last made, which was 2001. I was also told that my knife was in great condition and was a collectors piece - perhaps worth up to $500 or more. I can't even remember where I bought it - I think at a gun show in Seattle. I've got the knife and the pouch, but no box. I've never sharpened it and it appears to have the factory edge. I did invest maybe a whole 20 or 30 minutes trying to learn to flip it (over carpet). I've attached some photos showing minor scratches, scuffs and the things Benchmade mentioned they looked at to confirm it's authenticity. Unfortunately the scratches on the end of the knife and t-latch are more noticeable in real life that I could capture with my camera. The rest of the scratches and scuffs have to be seen under bright sunlight to be noticeable. What do you think is this knife's value?
