A survival knife is a versatile tool designed for outdoor activities and emergency situations. Typically featuring a fixed blade, it is made from durable materials like stainless steel or carbon steel. Survival knives often include additional features such as a serrated edge, a hollow handle for storage, or a built-in fire starter, making them useful for various tasks like cutting, carving, and preparing food. These knives are essential for campers, hikers, and survivalists, as they can help with shelter building, food preparation, and self-defense. When choosing a survival knife, factors like blade length, weight, and grip comfort are important to ensure effectiveness and ease of use in challenging environments.
