Abstract
The handheld cutting tool variants disclose improvements to the handheld cutting tool of U.S. Pat. No. 11,426,888B1/application Ser. No. 17/704,935. The handheld cutting tool variants deploying a razor blade have enhanced cutting made possible by either modifying portions or eliminating portions of the blade holder nosing which in turn is made possible by deploying either one of two newly disclosed blade restraint mechanisms. As with application Ser. No. 17/704,935/U.S. Pat. No. 11,426,888-B1, the tool is comprised predominantly of a handle body, a blade holder assembly which serves to deploy and constrain a replaceable blade and a rotational control assembly actuated by the user that enables the blade holder to rotate between retracted and a plurality of extended positions.
