A base has a top, a bottom, a left side, a right side, an upper section, a lower section, a left lateral section extending outwardly and upwardly from the lower section, a right lateral section extending outwardly and upwardly from the lower section, a left surface along the left side section and the left lateral section, and a right surface along the right side section and the right lateral section. The left surface and the right surfaces are each in a generally semi-cylindrical configuration and together form a primary gripping assembly. A head with an operational face faces away from the base. The operational face includes at least one left blade and at least one right blade and an arcuate sliding surface there between.
