What’s the Difference: Pin Gauges vs. Slicing Gauges
A closer look at these marking tools for scribe lines
Pin gauges and slicing gauges fall under the umbrella of marking gauges and are primarily used to scribe lines for joinery.
Pin gauges are simple and inexpensive. They consist of a steel pin mounted near the end of a bar that’s most often made of wood. Without refinement, the pin makes a V-shaped cut that tends to rip the fibers when marking across the grain, as for a tenon.
The bane of the pin. Marking across the grain with a pin gauge leads to torn wood fibers and a ragged cutting line.
On slicing gauges (often called cutting gauges), the pin is replaced by a knifelike cutter that typically is flat on the outside face and beveled on the inside. This wedge shape pulls the main body of the gauge tight to the edge of the stock and discourages the blade from wandering. This profile also leads to tighter…
