    C-rings have been around for millennia and have been made of countless materials, so how could it be possible to come up with something new? That something new was a shape, one that fit the male body more closely than any ring in the past.

    This is the second generation of the ergonomic stainless steel c-ring. The original Ergo is the same width all the way around, but this new version is thicker at one end than the other. One of the guys at our Chicago store thought it looked like a door knocker and we thought that sounded like a great name.

    The Knocker has some serious heft to it. Like it's daddy, it's arced, rather than flat, so it follows the contours of your body. In addition to giving it extra weight, the wider bottom makes it more intuitive to put on, with the thicker part going behind the testicles. You'll be amazed by how comfortable this heavy piece of metal can be!
