I'm curious--how come the 58mms have the LED in the scale, but the 91mms have it as a layer? Having in the scale would make the knife a bit thinner. It seems to me to just make the knife clunkier, although I will admit, after cleaning up a Wenger Microlight Esquire whose batteries had corroded (I had to pull the scale to get to the circuit board, I prefer the simplistic Vic LED assembly of just the bulb, batteries, and contact when that happens again.
