Thank you 9mm. Your experience is valued.
Systems that I have experience in have taught to have completed at least 2 cuts before you even get there
Likewise.
In your opinion, then, if you do find yourself in the advantageous position of being practically behind them, having already made at least two cuts, you would go for the throat? That's been my preference in practice, and I generally find that my knife is high at that point anyway and the throat is also the nearest target. There are just a few situations where I tend to find the kidneys the more immediate target, and given their use in sentry takeouts I am loath to dismiss them.
In a face-to-face knife encounter, you'd be better served by removing your attacker's ability to grasp their weapon, rise their arm and support their body weight.
Clearly you favour the biomechanical cutting approach. Of the three approaches it is the only one I don't doubt the theory of, because no matter how much adrenalin, amphetamine or whatever else is in someone's system, if tendons are no longer connected they will not work. Period. All that I do doubt is the practical application - my/your/someotherguy's ability to effectively make those cuts with a relatively short blade. For everyone who says it is feasible, someone else says it is not. If you have seen it working with EDC sized knives, I would really like to know.
I started out with cutting swords. Biomechanical cutting is obvious in that case. If I was using a 12" knife I wouldn't be concerned, either. Using a 5" knife - it ain't much to slice with.
5-10 seconds is a lifetime in a fight
Agreed. For a single wound, though, it seems quite fast. In a multiple opponent situation (which is, for me, the most likely situation in which I wouldn't be able to run away) where I don't have the luxury of continuing to press the advantage over a single opponent, it seems valuable.
Admittedly, a multiple opponent situation is seriously bad, but it really does seem the most likely situation in which my knife is drawn. It's the situation in which I am most likely to have it concealed in my hand before anything kicks off.
As said above, experience is valued, and I'd appreciate comments.
