Cutting system for soft materials using replaceable blades

A system comprising:

• a blade die having a first molding surface and a second molding surface;
• a first clamping caul positioned on a first side of the blade die, wherein the first clamping caul has a third molding surface that is complementary to the first molding surface;
• a second clamping caul positioned on a second side of the blade die, wherein the second clamping caul has a fourth molding surface that is complementary to the second molding surface, wherein the blade die, the first clamping caul, and the second clamping caul form a cutting assembly, wherein the first molding surface and the third molding surface are configured to bend a first interchangeable blade positioned therebetween into a first shape in response to a first compression force between the first molding surface and the third molding surface, and wherein the second molding surface and the fourth molding surface are configured to bend a second interchangeable blade positioned therebetween into a second shape in response to a second compression force between the second molding surface and the fourth molding surface, and
• a protective lid configured to enclose at least a top portion of the cutting assembly wherein the protective lid comprises a protrusion configured to contact a nut and prevent rotation of the nut while the protective lid is positioned on the cutting assembly and while a tightening bolt is tightened into the nut.
