The Adjustable-Length Screwdriver from Klein Tools features a shaft that adjusts from 4 to 8 inches in length. The shaft is removable and reversible with a different tip on each end. The proprietary system securely holds the blade in place and is as durable as a traditional Klein fixed-blade screwdriver. The screwdriver has a cushion-grip handle for maximum comfort and torque and is made in the USA.
