Two-Way Full Aluminum Ratcheting Precision Screwdriver (MP002027)

Very simple, small ratcheting pen, just add the tip you need and you're good. Now, this is not for heavy duty use, but great for smaller stuff like watches and stuff. It appears to be robust though.

Very nice tool of the highest quality, easy to use and a great bargain

I like the compact size of the rachet and how smoothly it operates. Putting it to work on edc folders next.
