Hi reisrdok - welcome to multitool.org

I'm afraid that as soon as you remove those bolts - the warranty is technically invalid. You might find that your local Leatherman service centre will fix it for, but they are within the terms of the agreement to refuse. Leatherman don't sell replacement parts, although it possible to sometimes find some on this forum, but rarely.
The screws that Leatherman use are proprietary, so you won't be able to buy a tool to undo them (at least none of us have ever found anywhere to buy them). You can use two Kick pocket clips as spanners, which work great on the smaller screws where the scissors and bit driver are, but the screws that hold the external blades are larger, so they are a problem to remove without doing damage I'm afraid.
I hope that helps a bit
