To say the truth, the reason I took this up is that I am searching a knife for "martial applications". Things going south where I live and so on. I have been thinking of Spyderco Matriarch, Yojimbo 2 or some Cold steel tanto. My logic is as follows:
The staight edge might be easy to maintain. I do have knife training (escrima and other skills) and also unarmed training. If the situation goes bad, I want to discourage the attacker by cutting, not stabbing. Snap cut in the Demko video looked devastating. Still stabbing can't be ruled out, I dont want to limit my choises. Therefore Matriarch is secondary choise, also because I want to use the knife for utility too.
