Cutting gauge plan
Cutting gauges are very similar to marking gauges, but instead of a metal spur, the stem carries a small knife blade held in position by a wedge. In the drawing the fence is fixed to the stem, using a M6 wing screw as a locking screw.
The cutting gauge is used for scoring deep lines parallel to the edge, especially across the grain when marking long shoulders of joints. It can also be used for cutting the sides of small grooves, or for splitting thin wood into strips.

Using the cutting gauge
Set the distance from the blade to the fence, and tighten the wing screw. To tighten the blade tap the top of the wedge with a small hammer or a piece of wood. To loosen the blade tap the end of the stem, and remove the blade with your fingers.
