ABSTRACT:
A tool having a palm knob that is joined to a handle with a connector. The connector allows the tool to be rotated without rotating the knob. The connector has a split head that fits into a countersunk recess to hold the knob in assembled relation with the handle. This allows the knob to be readily assembled on the handle without the use of any tools or additional structures. A washer coated with a friction resistant resin is located between the knob and the handle to laterally and longitudinally stabilize the knob relative to the end of the handle.
