The VG-10 blade is painstakingly laminated with carbon fiber, to make a composite construction. The one sided tanto grind (Kataba) is visually unique and super sharp. The patented Arc-Lock just might be the perfect lock. It is totally ambidextrous and has all of the attributes knife designers relentlessly search for, but rarely find. The Arc- Lock far surpasses conventional lock strength, tested at over 1000-Pounds of force measured at the lock in an independent lab test. The Arc-Lock provides lightning-quick, one-handed opening and closing capability. Spring-action securely retains the blade closed. When unlocking, the fingers are safely kept clear. The Arc-Lock is self-adjusting over time and can be easily cleaned for long-term optimal performance.
