Fixed blade knives make great tactical, combat, and self-defense tools because they are made to be tough, durable, and dependable. Fixed blades come in larger sizes and offer the strength that other types of knives can’t. In a tactical or combat situation, you can never go wrong with a fixed blade knife. The combat knife and the trench knife are examples of military fighting knives. Tactical knives are built for tough people working tough jobs in any situation. They’re perfect for tackling mundane chores around the house like opening packages or cutting thick cord in a rainstorm at night.
