Crisp, Hollow-Ground Radius Gives Much More Strength, True, Precision-Ground, Hollow-Ground Blades, Excellent Fit,Superb Control, Sizes to Fit Nearly Every Gunscrew - The New Standard By Which To Judge All Others
THE PERFECT TIP & BLADE
We started with the tip of the blade, the part that has to fit the gun screw properly, and the most important part of a gunsmith's screwdriver. The blade tips are then custom, precision-ground in a crisply radiused, hollow-ground shape to give maximum strength. And, the ideal parallel section is ground at the tip to fit the screw slot properly through the full width and depth of the slot. (This is what keeps you from buggering screws - a blade tip that evenly distributes the turning torque applied at the handle to the full width and depth of the screw slot.) We made the blades short (you're only 2½" from the workpiece) to give you maximum control, eliminate wobble and tilt. Yet, they are long enough to give you a good view of the work you are doing.
Tolerances are kept extremely tight for the entire blade, and the entire blade/shank is hardened to Rc 58-60 for proper, maximum strength and toughness in a screwdriver.
THE SHANK DESIGN
The long parallel shank maintains the same diameter as the width of the blade. This allows repeated regrindings and reshapings while still maintaining the original blade width. In addition, it allows the screwdriver to go into holes or recesses that are only screw-slot wide. The hex section allows you to use either an open-end wrench or one of the Midget Ratchets for more turning power on the heavier blades.
Finally, we put a size-sequence number - from 1 (smallest) to 20 (largest) on the hex section of each individual screwdriver so you can pick the size you want quickly.
HANDLE CUSTOM-DESIGNED FOR YOU
The handles are custom-made to our specifications to fit your hand well. They aren't too bulky, yet give a mighty good grip when large, tight screws have to be broken loose, and "fingertip" control when dealing with tiny, delicate screws. We use the same handle on all 20 screwdrivers to keep the same hand-fit and feel throughout the set.
