Tricks of the Trade continued from page 26 A Dovetail Marking Knife When transferring the shape of tails onto the pinboard of a dovetail joint, I like the accuracy gained by using a chisel-sharpened knife. As opposed to a double-beveled knife edge - which requires leaning the blade into the junction of the tailboard and pinboard - the flat side of a chisel-sharpened knife can be placed against the workpiece edge being traced, reducing the chance of error. However, it requires a right-handed and a left-handed knife. I decided to make a simple two-ended knife to do the job efficiently. The slim profile allows it to get into even the tightest spots. For the blade blank, I cut a 5"-long piece of metal from a V!2 "-thick discarded industrial hacksaw blade I got from a small metalworking shop. However, any heavy-duty hacksaw blade will work. I ground it down to a width of 3/s", removing the teeth in the process, while try- ing not to overheat the material. I radiused the ends on the grinder, then undercut behind each 3/8"-long cutting edge using the corner of the grinding wheel. I used emery cloth to break the sharp edges in the center for a more comfortable grip, but you could wrap it with electrical tape instead. After grinding a bevel on the same face of each end, I honed each bevel on the edges of waterstones.
