How to make a small chisel for delicate detail work

The small size of most inlay and stringing can require delicate tools to do tasks like cleaning and squaring up routed corners and edges. Even a 1 ⁄ 8-in. chisel is often too big, so I make my own small chisels, using jeweler’s files for the blades.

The two I use the most are a 1 ⁄ 16-in.-thick by 1 ⁄ 4-in.-wide flat chisel and a 1 ⁄ 8-in.-square chisel. Their diminutive size allows me to pare inside narrow grooves for stringing without damaging the walls of the grooves. These chisels are not difficult to make. All you need is a grinder to remove the teeth from the file, shorten its length, and create a cutting bevel that is then honed on waterstones. Like all chisels, these shopmade ones need handles. Any small piece of hardwood will do. After drilling a hole for the chisel tang and shaping the handle, I secure the chisel in the handle with cyanoacrylate glue. I do not bother hardening and tempering the blade, because the work these tools do isn’t demanding. But if you decide to do so, make sure to do it before attaching the handle.

Veritas Micro-Adjust Wheel Marking Gauge

The adjuster runs through the beam from a small knob at the back end right to the cutting wheel, which moves in and out as you turn the knob. This arrangement works well but makes adjustments a two-handed operation, requiring a little more effort.
