The amazing EDC-Key by Maratac™ was developed by EOD Robotics in 2008 for use by military robotics repair technicians.
This is the perfect pocket screwdriver! I used to carry a swiss army knife and used the screwdrivers frequently. I switched back to a traditional pocket knife but still needed a pocket screwdriver on a regular basis. This edc screwdriver fit that need very well. I really like that it will take any 1/4 bit. And best of all it's made in the USA!
