After the first fall of the golden city of Ayuddhaya, King Naresuan
the Great declared Siamese independence after the famous fight with
the Burmese viceroy on elephant back. The King's weapons were made from
the Namphi steel.
After the greatly expanding the Siamese lands in the reign of King Naresuan,
the golden era of Ayuddhaya was reestablished during the reign of King
Narai the Great. The regal sword of King Narai was made from the Namphi
steel blessed and charmed to negate and neutralize all evil and harm.
Khun Luang Sorasak, later used this imperial sword to vanquish the enemies
of Ayuddhaya in battle.
Khun Paen, the great soldier of Phra Ramathibodi the II whom legends
were told after possessed a Namphi sword called the 'Daab Fa Fuen'. The
eery making of this sacred sword can be heard in the Story of Khun Paen.
This sword is kept in the National Museum in Bangkok.
Phraya Pichai (the Governor of Uttaradit), the brave general of
King Taksin the Great (who declared independence from the Burmese after
the second fall of Ayuddhaya), went into battle with a Namphi sword named
"Nantakawut" in his left hand and an ordinary sword in his right.
After his victory, the righthand sword was broken and hence the name "Daab
Hak" or "Broken Sword". My belief is that the Namphi sword
in his left was used as a guard for protection and as a second weapon
due to the steel's superb qualities
5. Following the coronation of the past King Rama VII of (the current House of Chakri), Phraya Visetachai an officer of the Uttaradit province presented His Majesty with a sword made from Namphi steel. It is placed in the collection of the Royal Weapons (Phra Saeng Sastrawut) to this day.
The glorify Her Majesty the Queen's 60th anniversary, the world's
largest Namphi sword was created. It is 9.24 meters long, weighs 450
kilograms, involves use of 557.8 kilograms of Namphi steel, has a sheath
and a handle of Pterocarpus indicus wood embedded with pearl designs,
girdled with etched silver casings. It is now kept in the Uttaradit City
