Pro-Tech Cambria Plunge Lock Flipper Knife Black Al (3.5" Stonewash) CF01

First, let me say there is nothing wrong with this knife, it's beautifully made. There are just several things I'm not comfortable with, but they may occur with any flipper knife. I don't know, this is the first flipper I've bought. First concern, if you let the knife close itself, depending on the angle at which you're holding it, the blade may free fall into the case and bounce out again and inch or two. Of course you can do a normal two-handed closing perfectly well. When I first bought the knife, I called BladeHQ with some of my concerns. The person I talked to said he started using the knife in place of a fidget spinner to get used the action needed to effect a positive opening. Since that time, I have practiced opening and closing this knife literally hundreds of times and I still wouldn't rely on me getting it deployed in a stressful situation. I also am not fond of the radical change in had position to move from opening it to holding it. Of necessity your index finger which pulls the flipper has to be moved back around the knife handle to get a proper grip on it. I will use this knife around the house, and it's fun to play with, but I would never use it as an EDC because I don't feel comfortable that I could get it successfully deployed in a self-defense situation. YMMV.
