Starting a sword collection begins with research and understanding different types of swords—such as katana, broadswords, sabers, and rapiers. Determine your focus: historical, fantasy, or replicas. Set a budget and choose reputable dealers, such as antique shops, specialized stores, or online platforms. Start with a few well-preserved swords, prioritizing quality over quantity. Pay attention to details like the blade material, craftsmanship, and historical significance. Learn proper care and storage techniques to prevent damage.
