China?Japan?
 

Shape and creation that day originally, but be the haft China reformation?Age?
All lengths 97CM
The Japanese knife protects a hand.There is argent adornment.

In the book "Iron and steel swords of China" there are some very similar blades that are from the Ming dynasty. The tang is unusual, but consistent with what you would expect on a Chinese weapon rather than a Japanese one. Faceted dao blades like that are rare after the Ming, a time when there seems to have been considerable Japanese influence on Chinese weapons, returning styles that Japan had originally borrowed from China. The small hole in the guard is a bit confusing as that is found on Japanese guards, but not on Chinese ones. Still given the overall shape of the blade and style, I would guess this is a Ming period Chinese weapon.

Hmmmm
 

An excavated Korean piece perhaps......

Josh stout I agree you of viewpoint, this is really the sword of MING dynasty, however, I want to listen to the opinion of everyone's dissimilarity.
thank you

Korean would be a good guess, but I think the tang would be more angled like a Japanese piece, and have a hole for a peg rather than a peened end. Other than that, the triangular shape to the tang and the general look of the blade could easily suggest Korean.

Does anybody know of Korean examples with a peened tang?
Josh

Another suggestion??
 

Although described as a Khmer DHA by the original owner, I am rather inclined to think that is in fact a Cochin Saber (Southern Vietnam). I have not had the handle off so can't tell you what the tang is like, BUT the blade and "Tsuba" look remarkably like what you are showing.

What thoughts?

Chinese sword, Ming dynasty(A.D. 1368~A.D. 1683 )
 

Hi everyone
I am sure this is a chinese sword, and I have seen many similar pictures in China. It is true this sword looks like a japanese sword. Actually, this kind of swords were chinese copies of japanese katana, which were only used by a special troop who were fighting against japanese pirates and warriors in south China.
Pay more attention to handle of this sword, you guys can tell the difference between japanese katana and japanese copies.
