Thanks guys.  As I use it, one thing that I like over the flat boxes that you often see in combo plane sets is that the cutters  are easier to grab by the sides so there is less fumbling and tipping to get them out.    

Ducky, as long as the parallelograms have the same angle as this box, it will fit snugly in the drawer.   But now you've got me thinking that I need to make a non-square box for the plane itself.
