The Claymore (from Scottish Gaelic claidheamh mòr, literally "very big sword") is a large two-handed sword used by the Highlanders of Scotland. It was the mid-range weapon of William Wallace.

The average Claymore was about 55" in total length, with a 42" straight, two-edged blade made from carbon steel and weighed about 5.5 pounds. Most Claymores had a wheel pommel often capped with a crescent nut, and a guard with two down-sloping arms ending in quatrefoils. The handle was long enough to accommodate both of the user's hands.

The Claymore was a two-handed weapon and was used primarily for slashing, although it could also be used for stabbing. The overall weight of the blade combined with the strength of a two-handed swing allowed it to sever heads with ease.

The Claymore was tested against Shaka Zulu's spear. The William Wallace team claimed that the claymore was a one shot, multiple kills, weapon. They also claimed that Wallaces speacialty with the weapon was in decapitation.

To put this to the test, three skulls were placed on top of three different slabs of meat that were the same density as a human neck. The Claymore was to cut off all of the heads in one swing. Not only did the claymore easily lob off all three heads with one motion, it did it with increadible speed and power, making it Wallaces most effective weapon.

It was later tested against the Ishlangu shield, to see if the shield could stop the Claymore. The Claymore proved to be more than a match for the shield, going clean through and then nearly breaking the load cell it was being held on. The Wallace Sword is believed to be William Wallace's personal Claymore that he used in battle. It is shown in museums in the UK today. Fans were confused when the first historical mentioning of a Claymore was centuries after Wallace's life. Although the weapon did exist, it was classified and named as a large Broadsword at the time.
