The biggest advantage of the Etimo hook is the elastomeric comfort grip. It's revolutionary, supremely comfortable, functional, and durable with a soft, smooth, cushy feel and fits perfectly in my hand. Etimo hooks are made from durable superior quality aluminum with a polished finish that does not flake or chip. The handle's length, and depth of the hook make stitching easier.
