A conventional hacksaw requires a lot of effort and concentration from the operator not only for the accuracy of the job but also for his own safety. Although an electrical power hacksaw is a reliable option, the cost of the machine can prove to be high for small scale purposes. In this study, a crank operated reciprocating hacksaw is designed and fabricated. A slider crank mechanism is adopted in this design. The crank is rotated manually. This rotational motion is transmitted to the slider link, which is the hacksaw. The human effort is found to be much lesser than in the case of a conventional hacksaw.
