A survival knife is a versatile tool designed for outdoor activities and emergency situations. It typically features a fixed blade, which is stronger and more reliable than a folding knife. Survival knives often include additional features like a serrated edge, a gut hook, or a built-in fire starter, making them useful for tasks such as cutting rope, preparing food, or building shelter. These knives are essential for adventurers, campers, and hikers, as they can help ensure safety in the wilderness. When choosing a survival knife, consider factors like blade material, length, and handle design to find one that suits your needs and preferences.
