i LOVE my Ken Onion blackout... Cant say enough about it. I also cant stop playing with it. I use it everytime i can to cut something, wether it be rope or cardboard. My question is, im afraid thats its gona wear out, like one of my older knives that had soe sort of 'spring' in it to open it. Is the design of the speed safe dependant on a spring that is going to wear out eventually like m other knife? how does the speed safe actually work? What do you guys think about it? i know a lot of questions, but in new to the knife world... any help would be much appreciated.
