Saurons Weapon of Choice?

Then took or cut the Ring off his hand.

I doubt any Elf or Man could have taken down Sauron alone. In Letters #246, Tolkien gives this about Sauron's Third Age embodiment:

...in a tale which allows the incarnation of great spirits in a physical and destructible form their power must be far greater when actually physically present. Sauron should be thought of as very terrible. The form that he took was that of a man of more than human stature, but not gigantic.

That would really have been a weaker incarnation than that faced by Elendil and Gil-galad, since Sauron had been obliged to rebuild himself after the loss of the Ring.
So, I agree that it took three of his greatest foes working together to defeat Sauron, even when he apparently had no weapons but his innate spiritual and physical power.
