Well, the big knife was part of his point, as it was his service K-Bar, so you gotta grant him a style point there. Plus by having it on video, it does cut down on the number of claims of 'ethnic intimidation' charges.
How bizarre. As I was reading the story I was envisioning a Ka-Bar. A great knife (1450 carbon steel blade, a steel which easily takes a razor sharp edge).
How about this Ka-Bar? No joke, I have one in my wallet right this second:
Ka-Bar TDI LDK Ankle/Neck Knife, $14.99
