Fencing is the Martial Art of fighting with blades.
Kendō is the Martial Art of fighting with a Japanese blade.
Kendō uses a shinai or a practice (ie. bamboo) version of the katana,
the traditional Japanese blade.
Kendō differs from Olympic Foil Fencing, in that the katana is a curved,
cutting blade while the Fencing foil simulates a thin, stabbing blade.
