Although sliding bevels are not complicated tools, I learned that there are differences among them. Some differences are obvious and others are more subtle, but all have an effect on the quality of the tool. A sliding bevel consists of a body and a slotted blade that pivots on a machine screw or steel pin on one end of the body. A thin opening along much of the body accepts the blade. Manufacturers employ a variety of methods to lock the blade in place. A good sliding bevel will have a body and blade that are flat and straight and a locking mechanism that’s strong yet unobtrusive.  This small Kell sliding bevel easily fits into your apron pocket. The blade lock was difficult to tighten. And, because of the tapered design, it can’t be flipped to mark reverse angles.
