Synopsis: Brian T. Derber and his students evaluate a variety of benchstones to see how they measure up to Derber’s experience sharpening on razor hones. They looked at five types and explain why each is best for a particular type of job. Arkansas benchstones are good for high-carbon steel; Japanese waterstones can sharpen the hardest steels. Norton waterstones are an improvement over Japanese in some ways; ceramic stones are narrow but cut well; and diamond lapping plates are best for initial honing. A chart shows how the benchstones compare, listing their uses, pros, cons, and cost. A side article discusses how to know when your tool is sharp enough.

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.
