Every platoon has a knife guy and they're usually exactly like this dude. He loves the smell of burnt 550 cord in the morning. Do you know a knife guy in your platoon who always has a machete, Gerber or multi-tool handy to cut open an MRE at a moment's notice? This guy always has a Benchmade knife or twelve on hand. 

He always has about twelve steel knives that's over 5 inches, heck they're usually over twelve inches long. It's always an automatic knife or an OTF out the front style blade. 154cm preferably. He's cutting 550 cord, bringing a gun to a knife fight.
