The best Greek swords for modern martial arts practice include the xiphos and kopis, known for balance and versatility. The xiphos offers a straight, double-edged blade ideal for controlled thrusts, while the kopis features a forward-curving blade suited for powerful cuts. Look for high-carbon steel, full-tang construction, and proper weight distribution. These historically inspired swords provide durability, precision, and effective handling for safe and practical training sessions.
