At Havalon, they're redefining sharpness. Their longer-lasting, surgically sharp replaceable blades lock onto lightweight handles with their secure Quik-Change™ fitment, saving you valuable time and energy. Lightweight and effective, one knife and a set of extra blades gives the hunter enough skinning power for any animal – with no sharpening needed. Instead of carrying around a bulky set of knives and sharpening tools, or stopping to re-sharpen, with Havalon you can eliminate the extra weight in your pack and replace the blade as needed, and continue with your hunt.
