A protective riser guide for scissors is provided in the present disclosure. In certain embodiments, the protective riser guide is integrally formed with an arm of a pair of scissors. In other embodiments, the protective riser guide is removably attached to the exterior surface of a scissor arm. Preferably, the protective riser guide is in the shape of an arc extending away from the interior surface of the arm if the guide is integrally formed with the arm, or from the exterior surface if the guide is removably attached to the exterior surface. Due to the shape and position of the protective riser guide on the arm of a pair of scissors in certain embodiments, the protective riser guide is ergonomic and increases the safety of the operator of the scissors without interfering with the operator's cutting techniques. |

1. A pair of scissors comprising:
a pair of oppositely moveable scissor arms pivotably connected to each other by a pivot, the scissor arms each moveable about the pivot and comprising an arm proximal end forming a handle, an arm distal end forming an arm tip, an arm interior surface distal to the pivot and facing the other arm, an arm exterior surface opposite the arm interior surface, an arm exterior surface length extending from the pivot to the arm distal end, and an arm exterior surface width in a plane in which the arm is moveable about the pivot; and a protective riser guide, the protective riser guide having a base removably attached to the exterior surface of a scissor arm, the protective riser guide forming a symmetrical arc extending from the base to a peak, the peak opposite the base, wherein the peak is the furthest location along the arc from the exterior surface of the scissor arm on which the protective riser guide is removably attached, the protective riser guide and base each having a width substantially parallel to the exterior surface width of the scissor arm on which the protective riser guide is removably attached, the protective riser guide and peak each having a height substantially perpendicular to the width and length of the exterior surface of the scissor arm on which the protective riser guide is removably attached, the protective riser guide having a proximal end adjacent to the pivot, a distal end adjacent to the tip of the scissor arm on which the protective riser guide is removably attached, and a length substantially parallel to the length of the exterior surface of the scissor arm on which the protective riser guide is removably attached, the guide length extending from the guide proximal end to the guide distal end, wherein the scissor arm on which the protective riser guide is removably attached further comprises a cutting edge, wherein the height of the peak and the width of the base gradually taper from the proximal end to the distal end, and further wherein the height of the protective riser guide gradually tapers symmetrically on opposites sides of the peak from the peak to the base. |
