Got me several of these lying around. I carry one as EDC in my main pant pocket and a slightly smaller Smith & Wesson assisted opener in a lower calf pocket. Been a Schrade adherent for several years now. Started off getting one. Liked it a lot because of how well and rugged it is built. Then I saw them on sale for a song and nabbed a couple more.
There are many places where you cannot legally carry a handgun but I ALWAYS have a pair of assisted opening tactical knives on me wherever I am at and whether I am carrying a gun or not. 3.5" blade and the whole frame is one solid hunk of aluminum/steel with the rear of the handle doubling as a skull cra- I mean glass breaker.
If an attack is contact range or goes to the ground, one of these can instantly be deployed for a nice hefty dose of SURPRISE MUTHAFUCKA! I have done grappling situations in martial arts events with practice knives and when a fight becomes a grapple, you'd be surprised just how much stabby work can be done in a very short amount of time.
