I have been using a turned mallet that I made several years ago out of some laminated pieces of red oak. I still have it and it serves quite well to this day, although a chunk of it finally went flying a few weeks ago.
I finally got around to purchasing a set of Sorby sash mortise chisels and figured it was time for a respectable cabinetmaker’s mallet. I have access to a laser cutter at work, so I figured why not dress it up just a touch and have a little fun with it.
The head is left over hard maple from when I built my Roubo workbench a couple of years ago and the oak handle is from the scrap pile. The handle has about a 10 degree splay into the head and I put in some walnut wedges to keep it secure. It shouldn’t go anywhere for quite some time.
