FIG. 1 is a perspective view of a tool handle showing my new design;
FIG. 2 is a left view thereof;
FIG. 3 is a top view thereof;
FIG. 4 is an enlarged view of the portion of the left side of the tool handle shown in a dot-dash broken line circle indicated in FIG. 1; and,

The dot-dash broken line circles depict the limits of the enlarged views and form no part of the claimed design. The dot-dash lead lines in FIG. 1 labeled 4 and in FIG. 3 labeled 5 indicate the areas from which the enlargements in FIGS. 4 and 5 are taken and form no part of the claimed design.
