Forever Jump Rope / $75
No matter how well made, every jump rope will eventually wear out with heavy use. Despite its name, the Forever Jump Rope was designed with this in mind. Its handles are machined from solid 6061 aluminum, with precise fillets on the inside edges to hold the rope at a tangent as it spins. While the handles should last a lifetime, the black leather cord — cut from the center of the hide for maximum quality — is secured with simple knots at the ends, making it trivial to replace when its time comes. Each handle weighs 0.4 lbs., and the leather comes in a 10-foot length that can be cut and modified to match the user's size and jumping style.
