Apparatus for monitoring razor usage. The apparatus comprises an indicator means supported within a hollow handle portion of the razor and slidable to selected positions along the length thereof for alignment with numbered indicia on the handle to permit monitoring the number of times that the razor has been used. The apparatus provided may be used with razors of either the reusable or disposable type and can be incorporated into such razors with only minor alteration of the razor design.
