Do you think that High-elven blades could perce a dragons scales because when Gandalf kills the Balrog in Moria he uses Glamdring the High-elven sword used by King Turgon of Gondolin. The balrog can not be hurt by any mortal weapon and since Elves are not mortals an Elven blade was a kewy choice. But anywase tell me if you think the High-elven blades could pearce dragons scales if you say no then suport your theori and if you say no then say why and suport why you said no.
