This Navy Fleet's Knife Skills Routine Is Oddly Soothing

This is a troop of Korean Navy Seals in the middle of the vast oceans of god-knows-where.

Seemingly out of nowhere, they start practicing their knife skills routine, which is pretty awesome.

From the looks of it, knife combat isn't easy.

Look at that laser focus.

Just when you think you'd seen enough, the Seals started sparring with each other.

They move so fast it's crazy!

It's scary unbelievable.

They even perform routines with a comrade standing still as a target. The knives they are using do not have a sharp blade, but still.
