It gives me the leverage I need, and I can tap it and put weight on it as well. I use a similar technique for removing unbroken agraffes, substituting an agraffe bit for a screwdriver, and tapping occasionally with a hammer to loosen the threads. (Seems to avoid broken agraffes.) It also gives just the right leverage while spacing keys with the key-spacer bit, rather than having to use brute force to grip a straight handle. I sometimes like it with the backcheck tool as well, to rotate backchecks with greater ease and accuracy. Paul S. Larudee, RPT Richmond, CA
