FIG. 1 is a front view of a neurological hammer showing my new design, the rear view being symmetrical to the front view;

FIG. 2 is a left side view thereof;

FIG. 3 is a right side view thereof;

FIG. 4 is a top view thereof;

FIG. 5 is a bottom view thereof; and,

FIG. 6 is an in-use front view thereof.

When the hammer is in use as shown in FIG. 6, an impacting head is pushed up while two arcuate bulges are protruded from both sides of the hammer head, one of which lies in parallel to the shaft and another n perpendicular thereto. If necessary, a tip lying in a handle is extended therefrom by means of a turning device settled in the hammer handle.
