Alright Vietnamese swords
There are several different kinds of swords used in Vietnam. One kind is the Dao (butterfly/broad sword or saber). The Dao is of Chinese origin and is a single-bladed sword. it used with wide circular movements for attacks and is meant mainly for slashing and using strength in the shoulders helps. The Dao comes in different looks so not sure how to describe how it looks compared to the Chinese Daos.
Another kind of sword is the Kiem (straight sword). This is also of Chinese orgin, Jian in chinese. This is a double-edged sword that is lighter and thinner than the dao. this sword is used mainly for quick precise attacks and thrusts instead of slashing like the dao. also the attacks are performed mainly with the tip of the sword. not sure if its true but supposedly no other country in southeast asia uses this kind of sword. The Vietnamese kiem looks very much like the Chinese Jian, but there are some differences. one difference is that the blade of the Vietnamese kiem actually comes to a thin needle like tip compared to the Chinese jian which doesnt come to a needle like point.
In Vietnam however exists another sword called the Guom. This is real traditional/authentic Vietnamese sword of Vietnamese origin. (actually this sword can be called Kiem or Guom interchangeably but to keep from getting it confused with the double-bladed Kiem i'd stick with calling this Guom.) anyways the Vietnamese Guom is a thin single-bladed sword/saber. not sure how else to describe it but the blade is kinda like a Japanese blade but not quite. this sword is also typically single-handed handle unlike Japanese swords which favor two hands. Because of the design of the blade this sword is used for both slashing and thrusting. the movements and techniques are somewhat like the kiem as well. There is also a two-handed version of this sword with a longer handle which makes it look similar to the Japanese Katana but not exactly, probably has some Japanese influence. Some of the two-handed versions have handles that are more circular than the Japanese though and look different.
anyways sorry i dont have pics now. I'll try to find pictures some other time. for some reason i have hard time finding decent clear pics.
