So you might remember that chap with the impossible sounding name 'Vin Deisel' who spends altogether too much time driving his cars in what can only be termed an anti-social manner, of and he did a couple of Sci=Fi movies (which do not make up for that stinker XXX) From the Movies 'Pitch Black' & 'The Chronicles of Riddick' comes the nifty blades that Riddick always carried to good effect.
The Demon-Killing Knife from Supernatural is an ancient knife that was created by the Kurds which possesses the power to permanently kill most demonic entities. In the hands of Sam and Dean Winchester, it is bad news for any demon they come across.
So you have see the movies, you know all about the swords, but have you seen this dagger? No!!?? That's because it wasn't in any of the Movies, well..... actually.... it sorta was. This is a mini me version of the mighty Orcrist blade used by Thorin (and Legolas) in the Hobbit movies. Is it practical, not really. But it is cute!!
It may be small in stature but it is mighty in heart (sorta like some of the characters in the movies no?)
