I wanted an 8" long real saw edge (with offset teeth) down the side of an e tool. None of them have a large enough blade to achieve that, so I had to cut down a full sized shovel, straighten out the tang and reinforce it so that it could handle being used as a hatchet, nad added a removable D-handle. Cutting and offsetting the teeth with the angle grinder and the Dremel, etc. took half a day, and the rest of the work consumed nearly the rest of the take. The additional 1" of shovel blade width and 1.5" of increased length more than made up for the loss of surface area that was a result of cutting the very long angle down the side that became the saw blade. The extra bulk hasn't hurt its performance as a knife or hatchet, either. The saw is a lot safer and more discrete to use than any chopping instrument.
