I've seen a couple incidents where the issue was a rope wrapped around a wrist or body but not anchored or under tension. Obviously, they wanted the rop off and when they couldn't just pull it off easily, had to cut it off but didn't have the advantage of it being under significant tension. I keep a separate multi-tool with knife in my boat for everyday purposes.
