Here’s the neck strap ring on a Yamaha Custom Z alto sax that I was working on today. Notice that it’s made of stainless steel and not brass like on most other horns. If you have a quality neck strap with a stainless steel hook, after a lot of use, the stainless steel hook will eventually wear through the brass ring on the horn and you’ll have to have the ring replaced or risk dropping your horn. Yamaha was smart and added this nice little feature so you won’t have that problem. I wish more companies would put this much thought into their designs.
