I ordered some spilt rings from a supplier that was supposed to be spring steel but got a thick ring that when you open the ring to put a blade on it stays open. Does anyone know of quality rings that you can open and they return back to the original shape? I'm looking for No 1 size. I use these on underspins mostly 1/32, 1/16, and 1/8 so need a light weight rings that works.

Thanks, rhb
