I recently inherited a SOG PowerLock multitool and started a new building management job, I plan to EDC it. Doing a little research on the tools it has, I had to look up what the 1/4" driver is. That being said, I don't understand how this tool works. It's meant to hold bits, yeah? How does it do that? I like to think I know enough about tools to work with most, but this has me stumped. I tried doing a search, but couldn't find anything that would tell me how to use the tool. Any help appreciated!
