In Haedong Gumdo, we do not have free-style dueling (fighting) like Japanese Kendo or other martial arts but we do have many pre-defined duelings.
For this reason, Haedong Gumdo does not need heavy equipment like Bogu (armor for dueling) in Japanese Kendo.

The reason why we do not practice free style dueling is because Haedong Gumdo is really practical and does not want limitation of skills specifically designed for match.

Two-handed style dueling

Either bamboo sword (Jukdo)or wooden sword (Mokum) can be used for the two-handed style pre-defined dueling as this is not beginner's level.
In order to learn this style of pre-defined dueling, you have to finish Ssangsoo Gumbup, Shimsang Gumbup, Yedo Gumbup and Sunbang Gumbup number 1 to 10.

Beginning part (number 1 to 5) of this pre-defined dueling is one-versus-one style and intermediate part (number 6 to 10) is mainly focused on one-versus-many style duelings.
Advanced styles have more difficult and various techniques of practical sword fighting and are originally designed to be applied to battle fields practicals.
However, before you start to learn the numbers of dueling, you learn and practice lots of single dueling techniques first.

One-handed style dueling
In one-hande style duelings, we normally use bamboo swords for the practice because one-handed style needs more speed and fast application of sword art and needs the use of a lighter sword in general.

One-handed style is quite different from the two-handed style. It has its own stances, footworks, sword using techniques and applications. For this reason, many Haedong Gumdo schools do not eagerly teach the sword art style. Furthermore, chances to learn this style are only given to black belt students.

Students who finished Ssangsoo Gumbup and Shimsang Gumbup start to learn this one-handed style duelings. The beginner's level of this one-handed style pre-defined dueling mostly consists of one-versus-one dueling.
