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.
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.

5. The "drive-by" knife-hand
This fine display sends the message of, "stop being a f*ck-up" as you walk by someone who is probably going to f*ck up.

4. The "I can't believe you're eyeballin' me" knife-hand
Sometimes, recruits and other boots eyeball the instructors and they need a quick attitude adjustment. That is all.
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.
