: TOOLS AND THEIR USES
One of the most valuable tools in the whole set is the gage, but it is, in fact, the least known. This is simply a straight bar, with a sharpened point projecting out on one side near its end, and having an adjustable sliding head or cheekpiece. This tool is indispensable in making mortises or tenons, because the sharpened steel point which projects from the side of the bar, serves to outline and define the edges of the mortises or tenons, so that the cutting line may readily be followed.

This is the most difficult tool to hold when in use, but that will be fully explained under its proper head. Each kit should have two, as in making mortises and tenons one gage is required for each side of the mortise or tenon.
