Fixed-blade knives are tools with a blade that is permanently fixed to the handle, meaning they do not fold or retract. This design makes them sturdy and reliable, ideal for heavy-duty tasks like camping, hunting, or survival situations. The blade is typically made from strong materials like stainless steel or carbon steel, ensuring durability and sharpness. These knives come in various shapes and sizes, catering to different needs. For example, a hunting knife often has a curved blade for skinning game, while a survival knife may feature a thicker blade for chopping. Their simplicity and strength make fixed-blade knives popular among outdoor enthusiasts.
