To maintain your skinning knife for longevity, follow these essential tips. First, clean the blade after each use with warm water and mild soap, drying it thoroughly to prevent rust. Sharpen the blade regularly using a sharpening stone or honing rod to keep its edge sharp and efficient. Periodically oil the blade and handle, especially if it’s made of carbon steel, to prevent corrosion. Lastly, avoid using the knife on hard surfaces to preserve its sharpness and prevent damage to the blade’s edge.
