The Leatherman Micra is one of my favorite knives, but I don't really use the scissors. The flip-out multitool action is the signature feature of Leatherman knives; that's what makes them cool, yet I don't need that feature in the Micra. What I really want is a super tiny knife I can keep on my keychain without adding a lot of weight. With a simple modification you get a knife that is half the weight and half the size of the original. All you loose is one tool -- the scissors. I haven't found any knives for sale that are as small, light, and useful as my modified Micra.
Step 1: Locking pliers to remove hinge pin screws
A pair of locking pliers can be used to unscrew the four hinge pin screws that hold the knife together. I like to use genuine Vise-Grip locking pliers because they have a very sharp, clean edge.
The hinge pin screws have thread-lock in them so they will feel stiff coming out. They actually come out very easily, with little force, but you have to use the pliers the whole way while unscrewing them. You won't be able to loosen them a little and unscrew them the rest of the way with your fingers.
Step 2: Remove blades and organize
Remove the blades and set aside the blades that will be reused. Discard the rest.
Step 3: Adjust tension
The sides of the knife body will require a little gentle compression to adjust tension on the blades. Don't bend the sides in too much. The metal bends more easily than you might think. Squeeze a little, then test the pressure on the blades. Squeeze a bit more if necessary. The pressure is good when you can fit all the blades and they won't fall out even with the hinge pin removed.
