I messed up my marlinspike hitches on my last hang and ended up with two overhand knots in my webbing. I thought the webbing was toast. Not having a marlinspike to try to pry loose the knots, I got out a couple of screwdrivers and started inserting and prying, thinking that would never work. I was prying away while talking to a friend on the phone and was stunned when the knot came undone. The second knot was fixed during the same phone conversation. It really didn't take that much time.
Now, where do I find a diagram for how to tie my marlinspike hitches properly?
