I have a few multitools, but rarely use them. While better than nothing in an emergency, they are far inferior to a regular tool (screwdriver, file, scissors, etc.) My biggest use for one would be when traveling, where an inferior tool is still better than no tool. But almost all of them insist on putting a blade in there, so you can't take one as carry-on on an airplane. The few that don't have blades are generally of the "small, cheaply made, useless" variety in my searches. I've never used a multitool blade either. Those are significantly inferior to the regular pocket knife I carry.

I wish they would make a good quality, normal sized multitool that is TSA-friendly.
