My husband made me a soap cutter (single bar) and 2 plastic molds. The molds are covered with press and seal and put together and no leaks and it comes right apart with no tedious cutting and taping. The cutter can cut 3-1" bars lengthwise, or 1-3" bar widthwise any thickness in 1/4" increments just by spinning the stop 180 degrees and moving it back. He took a coping saw and took the saw blade off and put piano wire on it so it cuts easily through the soap. He Rocks!!!!
