Well I don't know for sure about the blades they "might" be able to be swapped when the time comes, they operate on the same technology that is in thier knives and folks take those appart all the time, this being double assisted and whatnot....don't know.
The scissors should can be swapped, they operate off the same locking system as the Powerlock 2.0, only difference is that it will take up two lock springs rather than the one required for the v-cutter. Hope this helps.
