A useful fish-scaling and skinning knife can be made of an old broken hacksaw blade. This must be at least 6 in. long and will make a knife with a 3-in. blade. Grind the blade to the shape shown and make a handle for it by using two strips of maple, 1/4 in. thick and 4 in. long. These are riveted together with 3 in. of the blade between them.—Contributed by John L. Waite, Cambridge, Mass.
