This is an especially handy knife made exclusively for Garrett Wade. It combines a solid but very slim 2-bladed stainless steel folding knife with a 6" folding precision rule graduated in 64ths, as well as a metric scale. Only 3/8" thick, it weighs only 0.8 oz. Length 3" closed

It's entirely unique and is easy to carry. You'll use its rule all the time - guaranteed.
