Developed with straight from-the-battlefield input of Afghanistan vet and Army Green Beret Jeremy Valdez, CRKT’s Septimo multi-tool is a do-it-all utility knife that features a 2.9-inch Veff serrated blade, an adjustable wrench, glass breaker, bit driver, and bottle opener. It weighs 4.4 ounces and a sprung pocket clip keeps it handy.
