Hi, I recently purchased a Boker KAL 74 B 50/50 to replace my Benchmade 580 which I lost while working. I chose the Boker based on reviews and cost. That being said, I would like to retain it. I am a wildland firefighter, and I often have to fly in helicopters and work in remote areas with difficult/unique terrain. I am trying to find a lanyard or retractable system that would allow me to secure my knife in my pocket. I use the clip to carry, but I don't want to have it come lose and fall out of the helicopter or my pocket. I tried just using simple P-cord, but it kept getting caught on things and it was a pain to unhook. Can anyone recommend any good systems that have a carabiner or are retractable? If there is a retractable system that allowed me to set the length that it retracts, that would be perfect.
