Hmmm ......you may not want to hear this either but I'm gonna put it out there anyways after reading the rest of this thread. Given the additional info about how safe it is back there, your other post about 1700 more acres to hunt predators, low funds, your intent to get a knife, and about " being prepared just in case" In lieu of a self defense type knife, you might consider getting a high quality lock back folding trapper and a can of pepper spray. Since you brought up statistics, statistically speaking it seems more likely to me like you would get a lot more use out of it skinning critters and cleaning crud out from under your finger nails than its doubtful use as a PD knife and the can of pepper spray is there in the unlikely event its going to be used.......just in case.
JMHO
Edit to add,
PM me you addy and I'll send you a knife that meets your criteria.......Free!!!!
It ain't much but the price is right and you will feel better with it and you can put your good money into a good knife that you will use for the rest of your life............
