Biscuits add gluing surface area

Take a look at the edge of a biscuit, that and a wee bit more is what material you are removing from the joint. Now look at the face of a biscuit, that is new long grain gluing surface that you are adding to the joint. Face minus edge surface area is positive and makes for more good gluing surface. You would have to try really hard to mess up an edge joint with biscuits. Biscuits are super fast, super cheap, very strong and a real aid in the wood shop.
