The Super Rope Cinch
The Super Rope Cinch™ is a simple handheld device that allows anyone to tie or untie rope with a simple twist. It can be used to tie or untie 1/8" to 5/8" rope, with nothing more than a simple twist.
The Super Rope Cinch™ is 100% waterproof, so untying wet knots are a thing of the past. It's strong, lightweight, and very easy to use.
