Abstract
A retaining spring clip includes an elongated body defining a longitudinal direction, a lateral direction that is perpendicular to the longitudinal direction, and a transverse direction that is perpendicular to the lateral direction and the longitudinal direction. A handle is disposed proximate to a first longitudinal end, an intermediate spring is disposed along the longitudinal direction, and a stepped groove is disposed proximate to a second longitudinal end. A triangular shaped void forms a backside of the intermediate spring, and a void filler is disposed in the triangular shaped void.

A retaining spring clip comprising:
- an elongated body defining a longitudinal direction, a lateral direction that is perpendicular to the longitudinal direction, and a transverse direction that is perpendicular to the lateral direction and the longitudinal direction;
- and
- a handle disposed proximate to a first longitudinal end, an intermediate spring disposed along the longitudinal direction, and a stepped groove disposed proximate to a second longitudinal end.
A blade assembly comprising:
- a plurality of retaining spring clips, each comprising:
- an elongated body defining a longitudinal direction, a lateral direction that is perpendicular to the longitudinal direction, and a transverse direction that is perpendicular to the lateral direction and the longitudinal direction;
- and
- a handle disposed proximate to a first longitudinal end, an intermediate spring disposed along the longitudinal direction, and a stepped groove disposed proximate to a second longitudinal end.
A retaining spring clip comprising:
- an elongated body defining a first direction, a second direction that is perpendicular to the first direction, and a third direction that is perpendicular to the first direction and the second direction;
- and
