ABSTRACT:
A small anvil is provided below the score line and is resiliently connected to a manually manipulated head above the score line such that the user can push downwardly on the head in order to deflect the sheet material through a desired bend angle along the score line. The head is resiliently supported from a block slidably mounted on an underlying table. The same table also supports the anvil, and the support preferably comprises support rods which extend obliquely inwardly from outside the edge of the sheet so that the head is particularly useful in trimming segments of plastic sheet of less than a foot in longitudinal dimension.
