The T-Driver™ is a great little pocket screwdriver for EDC (Everyday Carry) that provides the ability to increase torque by tilting the handle sideways making a T-Driver. The size of a pen, it provides three double ended bits, with a Phillips on one end and a flat bit on the other end. The sizes are Phillips #3 & Flat 1/4", Phillips #2 & Flat 3/16", and a Phillips #1 & Flat 1/8". Measuring only 5-1/8" long and weighing only 1.5 oz., it includes a pocket clip. This is a great multi-purpose screwdriver for any small tool kit or pocket carry.
For those who are familiar with Chapman tools and bits, They work jus fine on this T-Driver™. Because it is built to hold double ended bits, it provides just enough depth to utilize all the Chapman bits (Chapman bits not included).
