Compatible with the integral and removable leatherman bit driver - Leatherman Bit Kit Replacement #1

It's a long list on the box: Charge+ (and TTi), Skeletool (inc. RX and CX), Signal, Surge, Wave+, MUT, and Removable Bit Driver. I'm glad I didn't wait for an answer to my question, but ordered this to add the Torx bits for the Signal. It fits the driver (and I could use the pliers to twist the bits if they didn't). I bought the original in the mid-1980s, and while Dad didn't think much of it (Jack of all trades, master of none), he asked me to use it as we had to replace the outboard's broken shear pin while fishing a river in Montana. I enjoyed the company of one little frog on the gravel while removing and reinstalling the cotter pin, too. TSA nearly got one of the originals (I gave it to an airline agent as a Christmas gift for someone who'd appreciate it), as I'm accustomed to having a Leatherman on my belt, forgetting it's there until needed.
