Cosmanized Plane Adjustment Driver
If you use hand planes you need a screwdriver designed to fit tightly into the adjustment screw slots. You could use one of the screwdrivers from your toolbox, but the tip is probably not thick enough to snugly fit into the adjustment screw slots, making it easy to slip out and deform your screw slot.
Our Cosmanized Plane Adjustment Driver fits WoodRiver plane adjustment, tote, and handle screw slots perfectly giving you control, without slipping.
Our blade tips are 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 the screw slots - a blade tip that evenly distributes the turning torque applied at the handle to the full width and depth of the screw slot.
The shank is short (you're only 2½" from the workpiece) to give you maximum control, eliminate wobble and tilt. It is hardened to Rc 58-60 for maximum strength and toughness. The shank maintains the same diameter as the width of the blade. This allows repeated re-grindings and re-shapings while still maintaining the original blade width.
Finally, we wrap the handle with hockey tape to help ensure a good grip.

The head has been milled to fit the big screws on planes. No more damaging the brass screw head with a normal screw driver. If you have nice planes with brass screws you might want to think about getting one.
The proper fitting screw driver will save the finish on my Lie-Nielsen plane.
Works great. Thanks for all the stuff. Put the new plane irons and chip breakers in 2 older planes and makes a world of difference. Love the php t shirts too. Thanks Angie!
This screw driver has a thick flat head that locks cleanly into the plane's screw head without feeling loose. The hockey taped handle offers excellent grip as you loosen or tighten the screw at hand. Very solid feeling and not too large or heavy!
