I carried the original Gerber EAB for a long time, then carried an even Smaller Package opener tool for a little while.
I just got a Milwaukee Fastback 6-in-1 and it is pretty awesome.
I lost my EAB a few times because I could open it with one hand but was not comfortable closing it one handed so I would set it down and forget about by the time I was done with my task.
The Fastback is a lot bulkier but being able to easily close it one handed, and it basically being a nice full size screwdriver makes the extra bulk worth it in my opinion.
I wasn't aware of the c/pocketknife community. Thanks!
