SW1207131 Smith & Wesson Extreme Ops Linerlock GrayThe SW1207131 Extreme Ops combines a 3. 13" partially serrated 7Cr17MoV blade with a gray aluminum handle built around an extended tang for solid lockup and minimal flex. The linerlock mechanism paired with a thumb stud and pocket clip makes this a capable everyday carry folder that handles utility tasks without fuss. 7Cr17MoV holds an edge reasonably well and resists corrosion, a practical choice for mixed cutting work in variable European climates.
