9 photos that show how to execute perfect knife-hands

The knife-hand is a staple gesture in the military. It conveys a sense of power from those who use it wisely and temporarily cripples those who get one stuck in their face.

Delivering the proper knife-hand takes skill, and each one is special in its own subtle way.

9. The “re-adjusting” knife-hand

This knife-hand is being perfectly deployed to let this boot know his hand salute wasn’t up to freakin’ par. There, that’s better.

8. The famous “get ready for freakin’ boot camp” knife-hand

These knife-hands are meant to be up-close and personal with the “poolee,” as this is the first of many to come.

7. The “double-hand” knife-hand

This type of knife-hand is becoming an endangered species, as it takes a mighty human to deliver such a gesture. This double-handed gesture can be specially deployed when talking to a group of screw-ups.

It’s beautiful.

6. The “interview” knife-hand

This particular knife-hand is also meant to display power and convey a clear message of, “you better f*cking listen.” Notice how the general’s thumb is raised, not laid flat alongside his other fingers. Like Mattis, that’s a legit sign of a warrior.

4. The “I can’t believe you’re eyeballin’ me” knife-hand

3. The “are you freakin’ serious?” knife-hand

This excellent display of aggressiveness toward another soldier is remarkable. Some say there are no stupid questions. Well, in the military, there are — and this is how they’re met.
