KEEP IT SHARP: Replacement razor heads with sharp blades cut cleanly through the beard, avoiding beard pulling for a smoother shave. Older heads can become dull after a period of use, which can lead to an incomplete shave and leave stubble. Better fit: The parts of the razor head may deform slightly with use, affecting the fit to the face. Replacing the shaver head ensures a close fit to the contours of the face, especially in irregular areas such as the chin and neck, to better capture and shave the beard. Protecting the shaver body: Continuing to use a badly worn cutter head can increase the load on the shaver motor, making it work less efficiently and possibly even damaging the motor. Timely replacement of the cutterheads will reduce the strain on the motor and extend the overall life of the shaver. Reduce irritation: Older heads may have worn edges or uneven surfaces, which can easily irritate the skin during shaving, causing redness, itching, stinging and other discomfort.
