the only truly safe and effective cutting tool is a light saber: the blade can be retracted when not in use for safety, it will cut anything with relative ease (although i noticed those guys had a little trouble on those big steel doors in the last one) and you can clearly see where the cutting edge is at all times.....PLUS it will cut in every direction with equal ferocity. great tool...am building mine as we speak.....Happy Paddys Day to ya!!
