So a few weeks ago my friend was killed on a jump and it was determined that it was the risers that wrapped around his neck that killed him. Since then I've been told to keep a knife on every jump in case something like this happens to me. now I'm wondering what the best knife would be...I have a buck skinning knife that holds a fantastic edge and would probably work well, and I have a SOG with a seat belt cutting notch, but I was wondering if you guys knew of anything that worked particularly well for this application? basically I want something that will cut a thick nylon strap as quickly as possible. Any info would be gratefully accepted by several folks around here.
