Tweezers have two arms mounted on a spacer with a barbed tip at the other end of the arms. The tweezers are sharpened to the barbed tip with a belt sanding apparatus, which includes a holding device for positioning the tweezers on the belt sanding apparatus. A magnifying lens may be mounted on the spacer and positioned over the barbed tip to assist in sighting the foreign object to be removed.
