A channel forming region of a thin-film transistor is covered with an electrode and wiring line that extends from a source line. A hooked end of a pin is inserted into an inset hole aligned with a channel within the base plate. The cutter is arranged and configured to protrude from fence support through cutter slot to make a plunge cut into a surface of a workpiece when the contact surface is pressed against the surface and the cutter is plunged into the workpiece by pushing on a rearward handle portion of the tool. Device may be provided for adjusting the surface relative in distance to the resistance device during an exercise routine and or relative to the floor. In another embodiment, the cover is inserted into the outer metal and the split outer metal is crimped to secure the cover in place. The device automatically accommodates different height molds, as well as allows for different length pressing strokes, as well as different pressures, temperatures and rates of heating and cooling, and different durations of pressing to be individually controlled for each mold unit.
