Im not familiar with leatherman at all, but looking to get a small one for my keychain mainly for a small pair of scissors. I was looking at the micra and am wondering if there is a spring in the scissors to make them open on their own? Would appreciate if someone can weigh in that owns one and let me know how they cut. Or if maybe there is a different keychain multitool that is good quality out there. Looking to stay as small as possible. Thanks
