These burnishing rings are to obtain a wrinkle free finish on a bell taper by hand. The L19 Handle should be used for a weight advantage. Sometimes, instead of having it swing under the work, you lean it against your shoulder and push down as you work.
The L17 and L18 are each threaded on two sides to double the wear life of each the tool. Each ring has a cutout section so it may be used while the instrument is still together. These rings are chromed for a smoother action and longer tool life.
