Abstract
A handle system for a tool to fit the fingers of a hand of a user. At least two individual segments disposed adjacent to one another along a center sleeve. Projections and cooperating counterbores are formed on the edges of the respective segments such that the segments nest on the handle. The segments are axially slidable with respect to one another to accommodate the fingers of the hand. The segments may have grooves to receive the respective fingers. In a possible alternate embodiment, a center ridge is formed on each segment to be received between the fingers of the user's hand. In a system alternate embodiment, a removable handle system for a tool has individual axially slidable keyed or unkeyed segments on a center member. The center member engages the handle of the tool.
