Knife Hand

Knife hand is something the Marine Corps produced during the Second World War, specifically in the Pacific Theater to deal with Japanese Banzai troops, and those select few Japanese troops who wielded katanas.
The Ka-Bar although useful, had a few drawbacks. The biggest one, having to be drawn out of its sheath. In a life or death situation where time is of the essence, this just was a major problem.
According to legend Chesty Puller while fighting in the Pacific, exclaimed "Fuck these fucking samurai wannabes! I'll show them!", took his hand, using his fingers created a spade-like shape, and proceeded to knife hand hordes of Japanese Imperial soldiers.
The knife-hand also became a tool for military training due to its ambiguous nature of weapon, human parts, and has been scientifically proven to increase the learning aptitudes of the ignorant and not-so-smart types.
The knife-hand was thus adopted, and became a part of American history.

Chesty Puller's knife hand really fucked up a lot of Japanese fucktards.

"She dines in Hampstead village on expense accounted gruel,
And the jack knife barber drops her off at school."

Mary had an unexpected surprise, so she paid a visit to the jack knife barber.

lick the knife

To give it your all. A saying coming from how Eskimos kill wolves by having them lick frozen seal blood off of knives, therefore the wolves gave literally everything to lick a knife.

That actor left everything on the stage. They really did lick the knife!

buck knife

A knife manufactured by the Buck Knives company, which is one of many companies that produce cutlery. They make a wide variety of knives, both fixed and folding designs. Most are for hunting or everyday utility purposes, but a few are "tactical" (offensive/defensive) in nature.
To refer to a knife as a "buck knife" is not descriptive or useful at all. People need to quit doing that.

Idiot: That Jared Loughner had a 4-inch buck knife! He could've stabbed somebody with his buck knife!

Intelligent person: I have a small collection of pocket knives. My favorites are Buck, Kershaw, and Spyderco.

Idiot: Hey dude, check out my new buck knife!
Intelligent person: It has "Gerber" printed right on the blade, man.
