The ornamental design for a tipportion of a forklift fork, as shown and described.
FIG. 1 is an illustrative isometric view of a portion of a forklift truck, including a tip portion of a forklift fork including our new design;
FIG. 2 is an isometric view, at an enlarged scale, of the tip portion of a forklift fork shown in FIG. 1; and
FIG. 3 is a top plan view thereof, the bottom of the forklift fork forming no part of the claimed design and therefore not being illustrated; and,
FIG. 4 is a side view, with the opposite side view being a mirror image thereof.
The portions of a forklift truck and portions of the forklift forks shown in broken lines in FIG. 1 and FIG. 2 are included for the purpose of illustrating environment and form no part of the claimed design. The broken lines immediately adjacent to the shaded areas of the drawing views represent unclaimed boundaries of the design. The shading in the drawing views is intended to denote that the oblong outlined areas contrast visibly to the surrounding surfaces.
