These screwdrivers are very similar to our No. 553, except that they have a good feeling wood handle. There are many small, inexpensive screwdrivers on the market, but these were designed for superior quality and strength. Steel parts are nickel-plated. Blades are reversible, telescoping into the handle. Overall length with blade: No 559A, 4" (100 mm); No 559B, 6" (150 mm).
