> titanium out of the scrap bin. (Yes, I know that it will be nearly impossibly to cut off in an emergency,
Most commercial grades of Titanium can be cut with common tools. The tools will dull faster, but it's not impossible.
I suspect a lot of the stories about Ti rings being impossible to cut are coming from people who confuse Titanium with Tungsten. People get exotic metals mixed up all the time.
On the other hand, if you pulled it from the scrap bin you may have gotten some extreme aerospace grade of Titanium that really is difficult to cut.
Even Tungsten isn't particularly hard to cut. Also truly Tungsten rings are a lot less common.
Most of the rings referred to as Tungsten rings are actually Tungsten Carbide. Tungsten Carbide rings, by comparison, is VERY hard to cut. You basically need a diamond blade/saw/grinding wheel to cut through TC.
Yet, you (gently) smash it with a hammer and it breaks to pieces. By adding a block that is a bit thicker than the finger bone, you prevent smashing your finger in the process
