The Benchmade Adamas represents the pinnacle of tactical folding knife engineering, earning its name from the Greek word meaning "unconquerable." Designed by renowned custom knifemaker Shane Sibert with input from military personnel who needed something tougher than standard tactical folders, this legendary knife series delivers uncompromising durability across three distinct formats: the full-size Benchmade 275, the compact Mini Adamas 273, and the ultralight Benchmade Adamas Fixed Blade. Built to handle serious abuse while remaining surprisingly usable for daily tasks, each Adamas features premium blade steel that delivers exceptional edge retention and wear resistance even under the most brutal conditions. The signature AXIS Lock knife mechanism provides rock-solid blade security, while the textured G10 handles ensure a confident grip in any conditions. In strength testing, this outstanding mechanism suffered 1,717 inch-pounds of force before it gently failed, proving why military and first responders trust their lives to this overbuilt knife. Whether you choose the full-size tactical folding knife for maximum capability or the Mini Adamas for easier carry, you're getting a knife that's genuinely built to perform when failure isn't an option.
