Purpose built for heavy field use, the Guided Field Sharpener 2.2.1 from Work Sharp is quick to use and versatile. The sharpener fits perfectly in a field pack, truck box or pocket, and offers five stages of sharpening—two diamond plates, two ceramic rods and one leather strop—to give blades, hooks or broadheads the necessary edge they deserve. Work Sharp includes built-in angle guides for a consistent bevel. The sharpener comes with a hidden storage compartment behind the magnetic diamond grit plates, and a lanyard may be attached.
