...to a Lawyer Fight!
At 12:20, this Sad Monk literally just steps aside from being stabbed, what an absolute unit. Requested by Triforce Power.
Calc[]
So it was heading towards the left side of his body and he sidestepped right. To get distance, we'll use his shoulder width as radius of a 45 degree angular arc.
Radius = 18.25 inches, or 46.36 cm
Using this, that comes out to 36.41 cm moved. The knife was very close to his chest upon his dodging- let's say 5 cm (which is more than reasonable, if you watch the feat).
People here seem to believe 12 m/s is a reliable speed for swords, so a knife should reasonably be higher. 12 m/s will do.
S = 36.41 * 12 / 5 = 87.38 m/s, Subsonic
Neato. That'll do, pig.
