Ruko Knives Safe-Sharp Features The Ruko Knives Safe-Sharp combines a carbide blade and a ceramic rod in a single compact sharpener giving users both a coarse edge-setting stage and a fine honing stage in one tool. The Safety Orange GFN nylon housing is bright and easy to locate if set down in grass brush or a cluttered pack. At 3.50 inches long 0.88 inches wide and just 2.08 ounces the sharpener adds almost no weight to a pack or pocket. Its small footprint makes it a practical companion for hunting fishing and camping trips where a full sharpening kit is impractical. Beyond its sharpening function the Safe-Sharp integrates a high-pitched emergency whistle that can help signal for help if a hunter or hiker becomes lost or injured. A lanyard loop allows the sharpener to be attached to a pack belt or zipper pull for quick access when needed. The clamshell packaging keeps the unit protected for retail display and storage until it is ready for use. The Ruko Knives Safe-Sharp is a lightweight dual-purpose field tool for sale at GrabAGun.
