Ok, I got this many years ago and forgot about it until I just recently came across it in the safe. Bought it at a gun show in Atlanta and don't remember much about it. Story was no markings due to it being a 'sterile' knife, however the price was not bad and I bought the knife and not the story about it being some super-secret ninja killer made for some high speed military outfit. So can anybody tell me what I have? Closed length is about 5 1/4 inches. Open length is almost 9 1/2 inches. Blade length (straight line) is 3 3/4 inches. Sharpened length of blade is approx. 3 7/8 inches. Top edge of blade not sharpened. Blade, screws and button attract a magnet. Handle feels like aluminum and does not attract a magnet. I still have the red plastic mesh that encased it to keep it from accidentally opening. No safety lock or latch, press button and it jumps. It's got a very strong spring. It will finish opening and lock from any position the blade is in. Very solid feel and while I have never sharpened it, or used it, the factory edge is still sharp enough to shave. Thanks for the help.
