Traditional fixed blade knives typically have a guard, and have more traditional handle materials such as leather, wood, stag, or bone. Traditional fixed blades usually have leather sheaths. They sometimes have spacers in the handles, and rarely use screws to hold handle materials in - usually handles are pinned or peened. Of course all these "traditional fixed blade rules" are broken often, especially when a company remakes and revamps and older design or model. But if done right the knife still has that traditional feel to it. There's nothing like a quality belt knife at your side.
