Teeny Turner by [Picquic][1]. For those who wished wish to get a bigger handle, the small bits fits perfectly in their Multique screwdriver.
I'm using Picquic screwdrivers for the last 20 years or so (and I'm still using my very first one occasionnaly). When working at a customer site, I only carry in my pouch a Multique (default bit is Philips #2) and a Sixpac Plus (default bit is Robertson #2). Since the size of the handles are different, I know without looking at them which one I need for the task I'm doing.
