G'day John From below normal temperature. Minnesota Geswien in New Jersey, sells a rotary, hand turned, saw for just that application, and the blades don't break as easily. It looks like a pliers with a rotary blade on top .... The only thing I've found about using it is the customer, whom I don't charge for the service either, can't believe how fast and easy it was for me to remove there source of so much pain and worry.
Hi Robert, Thank you for the plug. We have several styles of ring
cutter like the one you’re describing but the most popular is the
Beaver Ring Cutter. We’ve sol d them to many jewelers as well as
hospital emergency rooms. And you’re right , it does a very fast job.
Gesswein is actually located in Bridgeport Connecticut. But we ship
anywhere and you can also see us online at www.gesswein.com Look

in “Beaver Ring Cutter” to see the type of tool we’re discussing.
