Dat Aaaaation Tho!
Rob I.
I'm blown away at the quality of the little auto blade. The tight tolerances, sharpness of the blade (out of the box), and the build material are all top notch! The coolest thing about this knife is how hard and fast it fires. That being said the one knock is there is no safety. Yes, it has deployed in my pocket and this bugger is so sharp I didn't even know I was cut. You've been warned.
