摘要:
A toothbrush is provided having an enhanced grip handle. The toothbrush includes a head, a neck portion and a handle, connected to the head via the neck portion. The handle may be provided with a multiplicity of small, inverted V-shaped protrusions. Each of these protrusions preferably have a substantially flattened vertex to promote easy and sure gripping by the user. In addition, drainage grooves may be disposed in the handle to drain water from the protrusions.
