Benchmade has the remains of a 970 (CQC 7) that was used by a technician checking explosive charges being set to demolish a building. This was the final check. The countdown was already underway. Since authorities had been notified, surrounding buildings evacuated, streets closed, etc., any delay at this point would have to be absolutely necessary for a very good reason. The technician unfortunately dropped his knife down one of the explosive-packed holes. to safely recover his knife would have taken several hours. So, he knew that he would just have to say good bye to his knife. Later, while checking the rubble for any possible undetonated explosives, the same technician came across the remains of his knife. As a joke, he sent it in to Benchmade for LifeSharp service. Benchmade replaced the knife.
Benchmade has the remains of an 812 (AFCK) that was dropped into a roaring campfire and recovered from the ashes the next day. That one was also replaced.
But, I like the story of the guy who quite literally blew up his knife best.
