80280 Set of Narrow Blade Screw Drivers
The screw drivers in this set are the size of jewelers screw drivers: they have the slim blades, swivel top and similar length. The difference lies in the diameter of the rubber sleeve just above the blades; it allows for a much higher torque, which is essential when using them on tight adjustment screws. It contains #0 and #1 Phillips and bladed screwdrivers of width 1.4mm, 2mm, 2.4mm, and 3mm. The 1.4mm and 2mm blades will work for recessed slotted set screws use for top adjustment screws in some jacks, while the two larger ones are good for #2 pan head screws used for top and botom adjustment screws. Screw drivers are also available separately.

8029 Plectra/Wire Handling Pliers
These 4 1/2" duck bill pliers have smooth (non-serrated) jaws, which make them ideal for inserting delrin and leather plectra into the tongues of harpsichord jacks and also for gently bending wire loops. They also can be used for squeezing delrin and leather plectra to reduce thickness. However, if used for this purpose, the inside jaws need to be polished with a fine file.
