I've been a officer with the state park police, assigned to the marine patrol for 5 years. I've carried a full size nylon rescue in an Uncle Mike's sheath on my uniform belt. Descrete and handy. I have a length of para cord attached to secure around the wrist when
performing utility tasks around deep water. I also have a second rescue in my PDF pocket, attached to the vest with a light cord.
I've used the rescue on countless occasions, making repairs, cutting line, removing line wrapped on a Jet Ski impeller shaft, you name it. During one rescue, I deployed the Spyderco to cut the sail lines on an overturned sailboat that my partner and I were righting in heavy seas. Usually we try not to damage any gear, but this had to be done in a hurry. With only one hand, the Spyderco worked great. I also have a remote release, but find the tension on the spring is not adequate, it can unintentionally come off. I know a few others with the same problem.
