Building combination handles
Andre Van Den Brink had the brilliant idea to make a combination of different handles, so you get all the benefits in one combination. Not like Prism a combo between ordinary handles and finger handles, but precisely customized handles that sit on your wrist. These handles will never slip out of your fingers by accident and end up on the ground. You can quickly choose between fitting wrist and finger straps at will without having to change handles. Brilliant!
Unfortunately we don't have a step description. You can get an idea by looking at these pictures (made available by Andre, thank you!).
