Weapon (d4)

By the way, Tolkien enthusiasts don't do that. They study Tolkien's biography, his works, the world of Middle-earth, its history, and culture, etc.
But role-players engage in fencing, and not with wooden swords, but with duralumin ones. And yes, what's wrong with that?

Well, yes, I agree, Tolkien enthusiasts and "Tolchki" are two different things. Quoting someone:
"What does some professor have to do with our hobbit games?" - That's the "Tolchki." And they also engage in swinging sticks. True, Tolkien enthusiasts have also come up with many things that the Professor didn't even suspect, but that's just a side note.
And regarding the material of the swords, you're wrong; I've seen wooden and textolite swords used by role-players. And even rubber axes and halberds have been encountered.
