The Signal combines traditional functional tools with new features for those who want to be well-prepared: a pre-shaped, diamond-coated blade sharpener for the care and maintenance of your straight and serrated blades. A flint rod and a safety signal whistle complete the package. Is the weather keeping you stuck at base camp? Do you want to make things a bit easier on this day hike? No problem. With the Signal, you are always equipped for all foreseeable and unforeseen situations, no matter where you are - the adventure can begin. A nylon holster is included.
