Patent ID: 7418760

Claim:
A tool for performing multiple functions comprising: a flexible member formed with a plurality of undulations; and a plurality of edges defined by a shape of said member and a curvature of said undulations, said plurality of edges comprising: a straight edge parallel to said undulations; a fingernail edge intersecting said straight edge at a first end, said fingernail edge having an S-shape and sinuous curvature; a rounded edge parallel to said undulations, said rounded edge disposed on a side of said member opposite said straight edge and having an end continuous with a second end of said S-shape of said fingernail edge; and a further edge having a sinuous curvature disposed on a side of said member opposite said fingernail edge; wherein said S-shape of said fingernail edge proceeds inwardly directly from said first end toward said further edge at an acute angle from said straight edge to a concave portion and then proceeds outwardly away from said further edge to a rounded convex portion, said rounded convex portion including a first rounded portion proceeding outwardly away from said further edge to a peak and a second rounded portion continuous with said first rounded portion, proceeding from said peak inwardly toward said further edge and then continuously to said second end of said fingernail edge; wherein a sharp tip is formed by the intersection of said straight edge and said first end of said S-shape of said fingernail edge making an acute angle with said straight edge; and wherein said concave portion of said S-shape of said fingernail edge is in a first undulation and the rounded convex portion of said S-shape of said fingernail edge is in a second undulation of opposite direction to the first undulation and immediately following said first undulation.
