What is Your Favorite ASOIAF Weapon?

Yeah, you read the title. Tell me what is your weapon of choice and why in this epic fantasy that GRRM has created.

Personally, Longclaw. It connects my three favorite characters in the series, Jon, Jeor and Jorah.[AGOT-ASOS] (/b "The noble house of the bear gave the Bastard his blade, and with it, the potential to become Lord Commander of The Night's Watch")
