Selected as one of 11 Popular Mechanics Editor’s Choice Awards, the patent-pending doubleVsquare was designed by carpenter Ray Atwood and introduced at this year’s National Hardware Show. This square, which lists for $24.95, has all the functions of a standard triangular square tool, plus it folds open to a 90° square and allows you to mark two sides in one motion (as shown in the above picture). When it’s folded flat, it gives you a larger straight edge. When it’s folded closed, it takes up the same space as a speed square in your tool belt or toolbox.
What do you think? Will it replace your layout square? Let us know in comments.
