It's all about control with Dahle's rotary pencil sharpeners. With the twist of a dial you can set the degree of sharpness for your pencil. Whether you need a fine tip or a blunt edged point, Dahle's Automatic Cutting System sharpens to your personal preference then spins freely to prevent over sharpening. These sharpeners not only give you the optimal results you desire but they also save lead. Our rotary sharpeners can easily be cleaned to remove any waxy buildup. Dahle Rotary Sharpeners easily accommodate standard graphite and oversized artist pencils. A mounting clamp is included but not necessary for portable sharpening.
