Knife maker, designer, and all around swell guy, Jens Anso continues his high tech carabiner series with V.6 - The Parabiner!The side of the Parabiner allows it to be used as a rope brake with paracord (or thin rope). What is a rope brake? Well a rope brake allows you to secure one end of your line without having to tie a knot. It is quick to set and quick to undo. It also has the added benefit that you can pull the line tight and set it (anybody that has tried to tie a knot while holding a line taut will tell ya you need an extra hand). The Parabiner also still functions as your EDC carabiner to clip your keys or other gear to whatever you need. And of course: it still has a built in bottle opener for your hydration pleasure! Precision machined in Jens Anso's shop. Note: Last two pictures of various metals are just to show features in action. Actual carabiner is in black finish zirconium.
