THE steel used in hacksaw blades is well adapted for making knives, as it can be ground to a good keen edge that stands up well under usage. The knife shown in the illustration was made from a hack saw blade % inch wide and about 1/16 inch thick. The blade part was ground off on an angle, as shown, and the handle was formed by bending a piece of sheet zinc in the form of a TJ over the back of the blade. Of course a more pretentious handle Hacksaw knife. could be made from wood, held in place with rivets, but the handle described answers the purpose very well and has the merit of being made quickly. The blade is ground like an ordinary knife blade, or it can be ground on one side only like a chisel. If used for a scratch knife the latter method of grinding it preferred by the writer.
