Built something new today.
It's a jump rope created from one piece of vegetable-tanned leather, and it's designed to last a lifetime.
The handles are made from heaving line knots, and the ends are secured with whipping knots.
My goal was to make a jump rope without any plastic handles, fasteners, or moving parts so that it could withstand any type of impact from being dropped, having heavy weights dropped on it, or other wear and tear one might experience in a gym.
