The blade of the sword measures 4 feet 4 inches (132 cm) in length and 5 feet 6 inches (168 cm) including the hilt.
The breadth of the blade varies from 2.25 inches (5.7 cm) at the guard to 0.75 inches (1.9 cm) before the point. The sword weighs 6.0 pounds (2.7 kg).
Editor's Note: Considerable energy has been expended proclaiming this sword not to have belonged to William Wallace, based on observations such as its form being anachronistic, lack of records and so forth. Ultimately it is a metallographer who is able to determine most accurately whether a sword blade is from a certain period or not, and as is so often the case with claims of forgery with regards to swords, no metallographer has had at this sword, in other words no scientific rigour has been applied to the examination.
It is my personal observation that claims of swords being fakes are generally made by persons wishing to big note themselves and that genuine inquiries need to engage a metallographer and not random individuals vexing themselves with speculation.
I reserve judgement on this sword. It may or may not have been Wallace's; and if it is not it is still a fascinating specimen. In the case of Saint Peter's sword there is some evidence that it may indeed by a genuine relic (a sword far older and one the 'speculators' would have previously argued undeniably a forgery) so I see no reason to rule the Wallace sword out until it has been thoroughly inspected and tested by a metallographer.
