One of our dealers asked me to create a version of popular brass key hook. The piece could slip over a belt loop or a belt, but it didn't rest nicely on either. I look at most design with sharp contrast... it works or it doesn't. Crap execution of a good idea cracked the door open for me on this one.
I made two devices that each work beautifully, just decide where you're hanging your keys, the belt or the loop. For the belt, have a look at the EZ~Slider.
This one has a patent. Everybody needs a Buddy. Comes standard with brass split ring, choose installed or on the side.
Brass. Made by hand in our foundry in Los Angeles.
