I don’t really know why I came to think of the adjustment possibilities for ski pole straps when I saw a bottle opener on the kitchen table. But for some reason I got an idea of how to adjust the length of the strap and how tight it should be around the wrist, with just one hand. After having broken my left forearm as a child, having the whole hand through the pole strap, I very rarely use the straps while skiing, except from long flat sections where I need to push myself forward. But then it’s really nice to have a good grip and support of a tight strap.
Apparently, I’m not the first coming up with a thought of one-hand-adjustment. Both Dynafit and Kang seem to have had a similar idea, and I hope that’s something they are happy with so I’m not on a dead-end road.
At least I’ve tested the idea now, and it seems to work really well. I cut out a primitive prototype from a piece of sheet metal, from an old nail plate, and drilled and filed until I could pull the strap through. The other end of the strap I screwed onto the grip together with the metal prototype, and … Voilà! It was perfectly possible to adjust the strap with just one hand – simply pulling the flap of the strap to tighten and pulling the loop to loosen.
Now I have to find a solution to the next problem. How can I most efficiently get hold of those pieces of sheet metal, the small “tighteners”? I can’t spend an hour making each piece like I did with the prototype in order to make more bottle-opener looking tighteners. The straps I’m developing with Weaver Textile are already adapted to my one-hand-adjustment idea, so now I must figure out how to make these tiny adjustment pieces.
