I may have lost track of this discussion but blades are deadly and can stop people fast when used properly. Distance is the challenge against a gun but in terms of deadly effect, a short movement can pretty much bisect a liver, a kidney, take away breathing, prevent the ability to grasp tools, leave intestines flopping about on the ground. They can also do a smashing job at making people not want to screw with you. They do a great job at getting people off you. All of these options are of course performed best with good training. Blades have a place somewhat like a 380/38. Great option when you cannot carry a pistol, or your pistol needs a friend.
Let me know if you are in DFW and want some stabby practice or an espresso.
