Sterling Dovetailing Blade/Ruler
The Sterling Dovetailing Rule is designed to fit other squares. We use it with our Lee Valley double squares and it works great. If you already own a double square, this blade is an easy way to upgrade it to a precision tool.
The Sterling “Dovetailing Blade” is an incredibly handy ruler for checking the squareness of your dovetails to ensure excellent fit and “gap less” joints after assembly. Regular size rules simply cannot reach into the spaces the Sterling Dovetailing Ruler can. The Dovetailing Rule is hardened, precision ground and finished with the same satin Chrome finish as the standard rule.
The dimensions of the Sterling Dovetail Blade are 4" long, by .330" tall on the taller end, .90" on the smaller end and .075" thick.
