Discovered in a private collection and brought to life. The late Kit Carson’s memory is felt strongly throughout the industry—it shows in the absolute reverence the knife world has for his M16® and M21™ designs. The M40® everyday carry folding knife is based on a legacy design. This version is reimagined with Deadbolt®, marrying classic design with contemporary innovation. Kit’s legacy just keeps growing. Kit Carson turned out a host of game changing knives from his bench in Vine Grove, Kentucky. The M40® is based on one of his relatively unknown custom designs. In classic Kit style, the 4” stainless steel spear point blade is all business. It’s been given Veff Serrations™ for powerful cord and rope cutting capability and is met with a glass-reinforced nylon and aluminum bolster handle that’s strong and surprisingly lightweight. The magic happens when you fire it up. The deployment action is quick and smooth with a flipper and IKBS™ ball bearing pivot system. It locks into place with Deadbolt® and will stay there—enduring incredible stress and weight—until it’s simply closed with the prominent button. The M40® is well deserving of a spot in this legendary lineage. How Deadbolt® Works Steel bolts interlock with the blade when it’s deployed to yield incredible strength. A prominent button sits at the pivot point for simple, intuitive disengagement without fingers crossing the path of the blade.
