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.
Overall length: 6.25 inches

It’s great to find a simple tool like this that both makes adjustments easier and reduces damage on your tools. Fair price and highly recommended.
To undo or tighten the wide slot on the screw of the plane blade / chip breaker a standard screw driver is useless. The chance of slipping and damaging the plane is always there. The hockey tape on the handle is such a great addition for grip
Nice to know I’m no longer wallowing out my brass screws on my plane.
this driver fits in the screw heads better than any driver i've ever had, with this i'm not worried about damaging the brass screws on my plane
I was tired of the screw heads on my WR 5-1/2 plane getting marred up by a regular type slotted screwdriver, like you can buy off the shelf from any old hardware store. You know the kind, has the tapered head. This little plane adjustment driver is just the ticket! Fits the hardware very nicely, and hasn’t munched the slots anymore on my plane. A must buy accessory tool if you want to make your plane’s hardware last a long time.
