Most people won't tell the difference. You? Look carefully at the design of the snap bolt. He is different from everyone else. This thumb stud is wider and slopes down towards the tip of the hook. Do you know why? I doubt. This means the user can snap it onto an amring loop or other rigid loop simply by pressing the hook. This is a nice quick way to use it, especially with gloves on. Just hold the hook on the body and press on it. CLICK!
