Watch this modern-day Samurai slice a BB pellet traveling at 217 miles per hour

42-year-old Isao Machii is a Japanese Iaidoka, master of Iaido. Iaido is martial art focused on controlled movements in drawing a sword, striking an opponent, cleaning the blood from the blade, and then re-sheathing the sword. Iaido started during the Japanese feudal system and is the foundation of modern Japanese swordsmanship.

Machii holds Guinness World Records for the most martial arts sword cuts to one mat (suegiri), the fastest 1,000 martial arts sword cuts, the most sword cuts to straw mats in three minutes, and the fastest tennis ball (820 km/h) cut by sword.

"This is about processing it at an entirely different sensory level because he is not visually processing it," said Dr. Ramani Durvasula, who was on hand for the BB pellet event. "This is a different level of anticipatory processing. Something so procedural, something so fluid for him." Machii agreed, saying he doesn't use his eyes, but can instantly visualize the trajectory of the object in his mind.

He is now headmaster of his own samurai school. See more of his swordsmanship, and enjoy the reactions of people watching him:
