Usable serrated knife with a 3.38" blade and 3.5" handle. Great for opening thick plastic bags and sawing through cardboard! The handle fits medium to small hands quite well. Originally created as a dedicated knife to be kept by the stove for opening wood pellet bags.The design is broken into 3 main components: the left and right halves of the knife, and the dowel. Print the left and right halves on their flat sides so as to give the knife as much strength as possible. You will need to print 3 dowels, which are to be glued into either one of the knife halves. With the dowels in place, glue the two halves together. It would be advisable to use some clamps or place weight on the assembly while the glue sets to minimize the gap between the two halves.
