Abstract
Cutting of a material, such as a textile or film, can damage the material. A tool is provided that utilizes vacuum pressure near a knife edge to increase a result of the cut. The vacuum pressure passes through a base portion of the tool that has a recessed portion effective to distribute vacuum pressure to one or more apertures extending around an insert of a core portion. The one or more apertures align with a void between the knife edge and the insert allowing for the void to transmit the vacuum pressure through the tool to the knife edge. A machine horn may then cut the material at the knife edge and couple the material with another material.
