The wood saw is slightly longer (mm or two) than the file.
The S44 review here shows a file in the PowerPocketPlier (item in front) and also shows over 3" clearance.
On my PowerLock, the little handle flaps do not permit items much longer than the file or saw.
The
wirecutter page on SOG's site includes a pic of it alongside a saw, and it is shorter.
So, with all that logic, length of the wire cutter should not be a problem on the PPP. As for width, the wire cutter specifies 2 spaces. If you can fit your knife blade and the file (file towards inside) right next to each other and still close the tool, then the wire stripper should have no problem clearing the plier head. Maybe someone can give a more experience-based answer on that before you disassemble and re-arrange to find out though.
