Versatile Multi-Function Sharpener The DMT GlidePro-Z is full of options. It has four fixed angle pull-through v-slots: One coarse tungsten and one medium ceramic in 25°, and another tungsten and ceramic in 30°. Choose the angle best suited to your knife. And because sometimes you need a different angle, the GlidePro-Z also has two ceramic flat pads, one coarse and one medium, for free hand sharpening, as well as a tungsten steel. Add to that Phillips and flat head screwdrivers, nonslip grips, and a lanyard hole, and you have a truly versatile tool small enough to fit in your pocket or tool box.
