I have tried a number of multi tools. They all work in a pinch. However, the one item that I use more than any other and that is why I added one to my key ring, is an alan wrench key to remove my Really Right Stuff L bracket. I shoot with a non pro sized camera and occasionally shoot with a battery grip. The L bracket does not fit on the camera when I add the grip. Therefore, I need to remove the bracket frequently. I have not found any multi tool that has an alan wrench as part of the tool set. I may look for the Swiss Army Cybertool mentioned above! The multi tool is a great thing to have, but I never travel without my alan wrench. Happy searching.
