For beginners, the best sword steels emphasize toughness, easy maintenance, and safety. 1045 carbon steel is inexpensive and forgiving, great for form practice. 1060 adds resilience for light cutting. 5160 spring steel resists shock and bending, ideal for repeated drills. Properly heat-treated 440C stainless can work, but avoid decorative stainless blades. Whatever you choose, look for a full-tang, tempered blade from a reputable maker to build skills confidently over time.
