No Living Man

[Hot, crispy nice hobbit]

It is really unfortunate that Prof T has to describe it such that there is no other way.

No other blade, not though mightier hands had wielded it, would have dealt that foe a wound so bitter, cleaving the undead flesh, breaking the spell that knit his unseen sinews to his will.

This in itself accounts for two notions:
1. It has to be a Westerness dagger: made by the Numenoreans of Arnor to counter Angmar.
2. It has to be a midget with hairs on his feet.

Mark that this by no means imply that the Old Skeleton will die once the conditions are met; the hobbit in question still have to open his eyes and aim straight for the shins...

It is a wonder why Elrond did not hire a band of hobbits armed with old antique letter-openers to guard his realm...
