Early swords, whatever long swords or daggers, western swords or China swords are all the main weapons in cold weapons era. The medieval European knights were good at swords using, they generally added a counterweight ball in their own swords hilt. The main purpose is to adjust the center of gravity of the sword blade, in order to adjust the balance of power and flexibility based on the user's wrist force. If the center of gravity tend to sword blade, then the hacking or piercing power would be huge, but not good for the wrist to spin, if plus a counterweight ball or counterweights, then it would be easier to control the wrist spinning.

 

For the Europe swords, it is generally longer and heavy, if we do not increase the counterweight balls in the sword hilt, it will be very difficult to handle this sword. In other words, the purpose of increasing the counterweights is to make the overall weight of the sword reaches the balance level of people’s wont, so that the users will be more comfortable when using the swords. There are many kinds of materials that can be used to prepare sword hilt counterweights, but tungsten alloy counterweight material became the most important material because of its great density which can have a larger proportion in the case of smaller volume.

 

The main ways to increase the tungsten alloy counterweights to the sword hilt hilt are by adding the tungsten alloy counterweights to the top of sword hilt and adding the tungsten alloy counterweights in the sword handle. The reason why to increase the tungsten alloy counterweights is that to remove the center of gravity away from sword top as can as possible. So this is an effective method to reduce the balance point and increase the weight of swords. Because the weight in the sword blade will be heavier, so it needs to be heavier than the weights in sword hilt at the same balance point. So increasing tungsten alloy counterweight to the sword hilt can make the diameter of sword hilt to be longer thus be easier to prepare.

 

The property of high density makes tungsten alloy easy to achieve the requirements of sword hilt counterweights without increasing the materials volume. The corrosion resistance and anti-oxidation characteristics then makes the swords hilt to avoid the corrosion and decay by user's hand sweats. The drug-free environment characteristics also make it become the most popular material among many environmentalists. Using Tungsten alloy sword hilt counterweights will make it more comfortable to be used.
