Honda Tadakatsu’s Kabuto

Origin
Honda Tadakatsu is generally regarded as one of Tokugawa Ieyasu's finest generals, and he fought in almost all of his master's major battles. He was called a fine warrior by many of the fellow masters of the time. Tadakatsu is often referred to as "The Warrior who surpassed Death itself" because he never once suffered a significant wound, despite being the veteran of over 100 battles by the end of his life and because he was never defeated by another samurai. His kabuto helmet, famously adorned with deer antlers, ensured that he was always a recognizable figure on the field of battle.
