I remember one guy trying to put 91mm pliers in a 58mm frame. Wonder who that was.
Edit: a thought; given the width of the 58mm frame seems similar to the 91/93mm frames, could the large blade be made shorter and put on there? So it would need to have its front half (with the tip) snapped off, and end reprofiled, but would it be possible given the space/liner, etc.?
Say a small blade and a combo tool opposite eachother... need a custom spring but it would be super cool if it worked.
