Some small layout tools I have made. The one on the far left is a sliding bevel of my design. It is designed to make it easier to lay out dovetails close to the edge of a piece of wood. The middle one is another dovetail layout square. Its odd shape enables you to rotate it with the little knob which sticks out, when you are near the edge of the wood again, where it is usually tricky to hold the square in place. The one on the far right is a simple little square designed to fit into the bottom of a dovetail where no other square will fit. It was a bit of a decadent luxury to devote so much time to cutting it out just for this one specific application, hence it is not the best finished in terms of polishing.
