Japanese-style gauges have tapered blades that cut wood fibers rather than tear them. This produces a fine cut-line, ideal for chisel registration and to prevent tear-out when sawing. These are well-made Indonesian ebony versions.
The single-stem gauge has a wedge-secured 7" stem and a 4 3/4" long fence that is rounded on the underside for smooth travel over surfaces. For marking and mortise work, the double-stem gauge has a 5 3/8" long fence and 6" stems that secure with a thumbscrew pressing against a steel rub plate to avoid stem marring.
Good-quality gauges at an attractive price.
