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 built-in fire starter, or a hollow handle for storing small survival items. These knives are essential for tasks such as cutting rope, preparing food, and building shelters. Many survival knives are made from durable materials like stainless steel or carbon steel, ensuring they can withstand harsh conditions. Proper care and maintenance are crucial for maximizing their lifespan and effectiveness in the wild.
