The handle is made of acetate and is black in color for a comfortable grip. The screwdriver has an overall length of 8-11/32" and is ideal for use in tight spaces. The heavy-duty square shank allows for wrench assisted turning, while the bolster reinforces the shank for hard use. The cushion-grip handle provides greater torque and comfort, while the precision machined tips ensure an exact fit. The "Tip-Ident" feature quickly identifies the screwdriver type and tip orientation.
