I would probably put my Charge in my back pack and carry a sak like the Super Tinker, Champ Plus, Explorer or a Climber.
If you need a mini screwdriver, then I would pick a sak with a corkscrew or a MT that has it like the Charge AL. The sak mini screwdriver fits great in the Juice MT that has a corkscrew.
I wear glasses so I will make sure I have that covered by either carrying the Charge, Juice c2 or cs4, or a sak that has the corkscrew.
