I build custom cabinets for a living and there are times when I need to add a hinge or door panel to a spot with very little clearance. This rectangular driver is just the thing for such cases. I've used other similar drivers in the past, but most of them needed more space to work or were difficult to hold. This driver is easy to keep and use. I don't use it every day, but when I have a minimal clearance situation where I can't use my big drill bits or screwdrivers, this is definitely my tool.
