The staircase saw cuts the housings in the stringers to take the treads and risers. The wooden backs of these saws stiffen the blades, act as a depth stop, and give you handles to hold. The exposure of the blade is adjustable by means of screws passing through the wooden stock into slots in the blade. Set the blade exposure to the desired depth, saw the sides of the housing until it bottoms out, and then remove the waste with a chisel.
The router really shows how the plane is a guided chisel. With a wood or iron body that rides on the existing surface, the router plane holds its blade extended below to shear a new level surface beneath the first. Wooden-bodied versions, using a stout iron from a plow plane were, even in the tool maker's catalogs, unkindly referred to as an "old woman's tooth."
Once you have sawn the sides of the dado and roughed out the trench with a chisel, set the router plane's iron with just enough depth to take the lightest trim of the rough bottom. Start the router from the outside edges and push (or pull) into the cut. Set the iron a little deeper and go over the whole trench again. Taking the wood down with many passes and resettings of the iron will give you a smooth bottom. Of all the planes, the router gives you the clearest view of the edge at work. Watch the wood and work with a kind of rocking, sawing motion, sweeping the edge diagonally through the grain.
