Winkler SD2 - STANDARD DUTY 2 - For some tasks, compact carry is better and, often, when fixed blade concealment is desired or required the Winkler Knives SD2 is a perfect option. The SD2 offers the same attributes as the SD1, but with a useful drop-point blade shape. Easy to carry and conceal, the SD2 can be worn inside or outside the waistband. Remove the clip entirely and this compact fixed blade fits perfectly inside a pocket. Add your favorite lanyard and carry the Winkler SD2 as a concealable neck knife.
