A safety cutter ring comprising:
- a blade,
- a ring shaped body and a blade receiver,
- wherein said ring shaped boy includes an opening at each of a front end and a rear end,
- wherein the blade receiver is formed on and extends from a bottom side of said ring shaped body and comprises:
- a cavity formed within walls of the blade receiver extending from said bottom side of said ring shaped body, wherein said cavity is configured to retain the blade,
- wherein said cavity includes an aperture within a bottommost wall of the blade receiver extending from said bottom side of said ring shaped body to allow for the blade to project outwards, away from the ring shaped body,
- wherein more than three-quarters of the blade is retained within the cavity,
- wherein the blade is fixed at an angle relative to the bottom side of said ring shaped body, and
- wherein a portion of the blade projecting outwardly from the cavity is triangular portion.
