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: Slotted Drive fits the WoodRiver plane lever cap screw, the chip-breaker screw, tote and handle screw slots perfectly giving you control without slipping.   

Our blade tips are custom, precision-ground in hollow-ground shape to give maximum strength.  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 adjustment screwdriver does it all

I use the adjustment screwdriver on the Woodriver 5 ½ plane. The screwdriver has a parallel tip that covers more than the depth of the screw slots (it is not shaped like a chisel found on cheap screwdrivers). It engages the screw securely and without damaging it. The screw driver reaches also the two "Frog retaining screw pins" (to lock the frog onto the base) easily without disassembly. The screw between the pins (that opens/closes the throat to control tear-out) can also be reached with the screw driver but in an angle. If you are careful you can adjust this screw without removing the tote (handle). The adjustment screwdriver is a good product to have if you care about your plane.


Works great! Amazing customer service!


My favorite item that I've gotten from Rob so far. Definitely a thumbs up.
