This is a nicer saw package than described! BLADE CRADLE - The kit comes with a plastic blade cradle that will hold 4-5 blades. It includes a spring clip retainer to hold the blades securely in the cradle. This protect them from damaging the saw or bag when storing blades in the bag. 90° FINE TUNING There is an adjustable allen set screw that allows you to set the blade at exactly at 90° using a square. Although most c-saws have this feature, Dewalt doesn't mention it anywhere except the manual. This is the "stop" that returns the saw to exactly 90° after using the normal lever controlled bevel adjustment. This "fine tuning" should be done when you first get the saw and whenever you install a new blade.
