Claim 0:
1. A utility blade, comprising:
a first blade retention feature positioned on a proximal edge of a tang of the utility blade, the proximal edge being angularly offset from a longitudinal axis of the utility blade, the first blade retention feature being associated with an engagement axis parallel to the longitudinal axis of the utility blade, the utility blade being configured to translate along the engagement axis to cause the first blade retention feature to engage with a first blade engagement component of a blade holder;
a second blade retention feature positioned on a second edge of the tang of the utility blade, the second blade retention feature being positioned along the longitudinal axis of the utility blade and between the first blade retention feature and a distal tip of a cutting portion of the utility blade;
first and second angled edges, the first angled edge connecting the proximal edge and a first edge of the tang, and the second angled edge connecting the proximal edge and the second edge of the tang; and
the cutting portion extends proximally a cutting distance along an edge of the utility blade from the distal tip,
wherein:
the first blade retention feature is positioned on the tang at a first distance along the longitudinal axis from the distal tip, where the first distance is greater than the cutting distance;
the second blade retention feature is positioned on the tang at a second distance along the longitudinal axis from the distal tip, where the second distance is greater than the cutting distance and less than the first distance.
