The Beacon Hills student assassin Garrett is carrying around a knife inside his lacrosse gear.
The shape of this knife is different, but isn’t that original.
The knife pictured below is the knife used by the character Shinzon (played by Tom Hardy) in the Star Trek movie “Star Trek: Nemesis.”
The knife in Nemesis is based on a knife apart of a series called “The Fantasy Series” released by Gil Hibben and United Cutlery. The knife itself is called “The Double Shadow.” However, as far as I’ve seen it is really only a knife to be used for decoration and not for use in vigorous situations like actual combat. (Source)
[I’ve heard that a version of this knife shows up in “Expendables 2” but I know nothing about this franchise.]
I have seen some arguments for the space in the blade to be used as some sort of “catch” to ensnare an attackers weapon, but doesn’t seem at all practical considering how the space actually can make the knife weaker. Also trying to sharpen such an oddly shaped blade can be difficult.
So I’m really not sure how some properly trained killer is supposed to think this knife is supposed to be considered practical or even a great option for the work he’s planning to do with it.
[Don’t get me started on, “The Collective” bs.]
