I have owned a Lee Valley Veritas plane screwdriver for some years and indeed can recommend them for removing and setting the cap iron screw on all bench planes. We have many planes to work on because of our work and then the school of woodworking also. They seat nicely in the screw slot and the surrounding brass ferrule works to capture the whole head of the setscrew for a non-slip solidity to what is often awkward with a screwdriver. Recently, our film maker and editor Eloise was using an unwieldy screwdriver in the slot of a camera mount screw to remove the setscrew. Finger tight is usually not enough and many camera tripods do not use the butterfly thumb turns to secure the slide mount to the camera. Anyway, it looked awkward and I remembered my Veritas plane screwdriver. I said try this to see if this fits and it did indeed fit perfectly. She was thrilled with its dead on functionality and its non-slip solidity, so here you get two functions for the price of one and for any photographer-come-woodworker it’s a perfect Christmas gift at a low cost of $15.90.
