When I was choosing my tungsten ring one of the big things that the salesman really drove home for me, saying it several times, was the fact that with a ring, if anything happens to your finger,…
…cannot be cut off. It’s tungsten. It’s almost as hard as a diamond! A diamond cutting tool will have trouble..
That did make me pause. At the same time it’s an awesome ring! Sometimes a guy can brag about.. It was beautiful yet manly.
And I thought to myself, it also will protect my finger if anything should ever happen to it. In other words, if I get my hand on the door, chances are my hand is not going to get crushed because that ring is so tough, it won’t budge, it won’t break, it won’t bend… they’ll have to cut the door off around it. 
But yes, if your finger should swell up or get mangled somehow and they can’t get that ring off by sliding it off, you really only have two choices: 1) Wait for the swelling to come down and work around it and 2) Cut the finger off!
I’m just saying… it has to be part of your decision process. For me it was worth the risk. I had to think, What are the odds of that scenario really happening?
