1] The ergonomics are horrible. You hurt your fingers trying to open the pliers, sometimes. 2] The pliers don't have springs so when you're trying to cut or crimp something, you feel like the ticket conductor on a bus in a third-world country 3] The Blade is half straight, half serrated. So I guess it's good for saving space 4] The blade, the Belt cutter, the Screwdriver, all of them have locks. 5] Well overall I like the tool. It has a Minimalist design, good for everyday carry, but I wouldn't really recommend it to anyone. I sold my previous one to a friend, and later saw it was out of stock at the store I got it from, so I decided to get this one as a substitute.
