A razor head is provided with an anti-friction element firmly secured to the razor head. The anti-friction element is formed of a sole and an upper layer. At least the upper layer contains a water-soluble polymer. The upper layer is secured to the sole such as by bonding, molding, coextrusion, overmolding, or twin-shot injection molding. The sole then is secured to the razor head by welding.
