Krabi Krabong is a Thai fighting system which makes use of various weapons and also incorporates the empty-hand techniques of Muay Thai.

The empty-hand techniques use pressure points, locks, holds, and throws. The weapons techniques include training in these weapons:

• Krabi, sword
• Plong, staff
• Ngao, bladed staff
• Daab Song Meu, two swords, one in each hand
• Mae Sawk Sun, a pair of clubs which are worn on the forearms.

Practitioners learn to use each weapon effectively against any other weapon.

The foremost school of Krabi Krabong is the Buddhai Swan Sword Fighting Institute , in Thailand, which was led by the Grand Master Arjan Sumai until his death in 1998.
