We assessed the first Infidel prototypes and a couple other auto knives they were submitting for NSNs. When all was done, later on, they gave us a healthy discount on whatever knife we wanted. I got this, TM SGT got an Infidel, and I don't remember the others. At the time, they were special order one-offs from their military sales guy - they put our initials on them and our crest. This was in 2006 and they weren't doing a lot of one-offs or kept track of them or something.
My buddy who went to work for them when he told me this left to Kryptek around 2013-2014 ish. He may have been bullshitting but it's a good story. The new mil sales guy they had in 2015, saw it and told me to put it in the safe and gave me a discount off my next one. He said the full-size Ruckus is almost impossible to find and when I look them up, they're more than some Randalls.
Now, all the laser etched custom knives are a dime a dozen and not so special anymore.
