Gathering of the Pack 2010
Check out the video here. In the latest Dog Brothers video we see many fighters carrying a blade, and once combat closes to grappling range, blades come out. I think this is a compelling argument to being able to hit someone hard enough that you can drop them, stun them, or immobilize the (i.e. shot to the knee) before they can close and cut you.
Note the interesting two-handed strike at 1:30.
Several interesting exchanges occur when fighters are so focused on the weapon, whether sticks or knives, that an opponent’s kick gets in and hits huge.
