Which do you think was the greatest weapon in Arda?

[Grond]

If you'll look at the picture in this link http://thetolkien.forum/showthread.php?s=&postid=146002#post146002 of Melkor wielding Grond as he battles Fingolfin (painted by John Howe) as well as the painting Melkor and Ungoliant by the same artist linked below... you will see that Howe apparently envisioned that Grond was both hammer and spear. It appears that he is wielding Grond at both times and that he used the sharp end of the long hammer to pierce the two trees of Valinor. Of course, he ain't the author... but, of course, I like the sentiment.

Also note Melkor's appearance and how similar he appears to the Sauron of the movie.

 

[Gil-Galad]

hey Grond,as I can see you was a kind of "multifunctional" weapon.A spear and a hammer.Two things in one-quite comfortable I would say.
