これはKENDOです。朝鮮の伝統剣術は片手で剣、片手に盾を持ちます。そして両刃の直刀。両手に剣を持つのは日本の侍だけです。 This is KENDO. Korean tradition fencing holds a shield in sword, one hand with one hand. And a double-edged straight sword. It is only a Japanese samurai to hold a sword in both hands.
Real blades are heavy, and you have to take into consideration of edge placement since not all swings results in a proper cut. But blades are so dangerous that few people ever get to practice sparring with one.
