Ring saw

A finger ring saw (technically also ring saw pliers ) is a medical instrument for removing finger rings or toe rings if they can no longer be removed due to swelling or injuries. The ring is destroyed by cutting and then bent open.
With the help of the finger rings saw, rings made of metals and plastics can be cut easily and simply without the risk of injury directly on the finger. The lower part of the instrument consists of a slightly curved bracket that is pushed between the ring and the finger. On most models, the round saw blade can be turned with a large wing lever. Due to the low speed, there is hardly any frictional heat. For stainless steel and titanium or precious metals such as gold and silver , saw blades with different tooth pitches are used. Cutting through a ring made of stainless steel usually only takes one to two minutes, depending on the thickness.
Rings made of tungsten carbide cannot be cut through with a finger ring saw due to their hardness. In an emergency, however, these can be broken with locking pliers. Protection against the flying fragments is required.
Trivia
In the opening credits of the crime series Crossing Jordan - Pathologist with Profile , a finger rings saw was shown in a cloud of blood in addition to other medical equipment from season 2. This gave the impression that it was an autopsy instrument .
