We've been looking for a titanium split ring for ages, and McGizmo did some design footwork, and had two made. We're proud to carry his split rings. The small (15mm) and large (32 mm) split ring are now shipping! The large split ring works well with our new ti mini clip has reasonable memory for returning to original form after adding keys or the clip itself. The small split ring will easily deform leaving a slight gap between the coils if it is opened too much. These smaller split rings are available and I have used some successfully on a number of applications. However, they do not have the ideal springiness or memory that most common split rings have.
