For those of you that have a backup to your primary carry what do you normally use?
While it is true that the information posted is debatable, the idea that you can cut tendons to impair function, much less large muscle groups like the biceps and triceps with a knife is pretty unlikely.
The knives that most of us carry i.e. 5" blades and under are essentially "hand assistors", nothing more.
If you have a bolo, Bowie, or kukri then the idea of cutting tendons and large muscle groups comes into play but disabling those with the knives we carry is unlikely.
I have seen somewhere on the order of 3-5 stabbings/cuttings each week for over 15 years and hospital personnel in the ER see more and I have yet to see a cutting (as opposed to stabbing) that occurred with anything smaller than a sword that disabled a body part or muscle group.
This does not mean that such cuts will not cause psychological stops which are far more likely and most likely what are observed by those who claim to have witnessed a physically disabling cut.
What this means for knife use is that you generally want your knife methodology to be point-driven rather than edge-driven i.e. stabbing vs. cutting, and you want to target the same places you would if you were using your hands to strike i.e. the face/throat and the genitals.
A simple way to remember is that you want to drive the point to a place where the suspect: a) sees b) breathes c) breeds, until you achieve the desired result.
A knife has no shock effect like a bullet i.e. rapidly expanding gasses so the only power a knife has is that with which you drive it.

As I understand the current oklahoma knife laws any fixed blade by description (the description covers everything that I could think of) not being carried during stuff like hunting and fishing. I've been wanting to carry a neck knife but not in Oklahoma...it's insane, our knife laws are much stricter than our gun laws.
