Awaiting the arrival of my recently ordered "Clever Girl", I'll report more after trying in practice, I'm looking for that last ditch surprise that leaves a sting and causes immediate release and from what I've seen the clever girl is more that capable, of course you would also want a defensive blade that is capable of more should things go from bad to worse and not being overly skilled in knife combat I would again look for a knife that is less likely to be seen in the darkness of an alleyway, the blade length on the clever girl would allow for more serious wounds if necessary and it's apparent balance point and sleek design coupled with the low weight permit quick undetected thrusts, all this is in an attempt to withdraw from the situation as quickly as possible while hopefully sustaining no injuries, having said this i want to add that at no point in my 63 years have I ever looked for or anticipated a knife fight, the thought alone sickens me but, God forbid, I end up in a scenario such that the knife would be required rest assured I will do what ever it takes to be the combatant that goes home. If you watch the video provided by the creator of the clever girl, Austin McGlaun , you'll see how swift and deadly the knife can be used, he's a huge former soldier yet he is blindingly quick with the knife, it's just a blur of motion and at 4.6 inches in length the blade is able to reach vital organs, can't say the same for the other two.
And last but not the least CRKT donates 10% of each sale to the green beret foundation who in turn use the proceeds to aid returning servicemen with their ptsd treatment expenses as well as any number of things causing problems for our troops that the VA either takes too long or doesn't offer assistance at all, that was a major deciding factor for me.
