With this little tool, sharpening pruners and loppers is easy. Simply swipe it along the existing bevel of the blade.
This 280x diamond polycrystalline sharpener is a one-step tool that leaves a nicely sharpened edge. At 7-3/4" overall, it collapses to 5-3/8" to fit neatly in a pocket, and provides both a flat surface for sharpening pruners, loppers and scissors, and a half-round surface to accommodate serrated edges. A narrow groove on one face will even sharpen fishhooks.
Good value, this is an effective tool that can be used for numerous tasks.
