The word claymore was first used in reference to swords in the 18th century in Scotland and parts of England to refer to basket-hilted swords. This description was maybe not used during the 17th century, when basket-hilted swords were the primary military swords across Europe, but these basket-hilted, broad-bladed, swords remained in service with officers of Scottish regiments into the 21st century. After the Acts of Union in 1707 when Scottish and English regiments were integrated together, the swords were seen as a mark of distinction by Scottish officers over the more slender sabres used by their English contemporaries: a symbol of physical strength and prowess, and a link to the historic Highland way of life.
Two-handed (Highland) Claymore
The two-handed claymore was a large sword used in the late Medieval and early modern periods. It was used in the constant clan warfare and border fights with the English from circa 1400 to 1700. Although claymores existed as far back as the Wars of Scottish Independence they were smaller and few had the typical quatrefoil design (as can be seen on the Great Seal of John Balliol King of Scots). The last known battle in which it is considered to have been used in a significant number was the Battle of Killiecrankie in 1689. It was somewhat longer than other two-handed swords of the era. The English did use swords similar to the Claymore during the renaissance called a greatsword. The two-handed claymore seems to be an offshoot of early Scottish medieval longswords (similar to the espee de guerre or grete war sword) which had developed a distinctive style of a cross-hilt with forward-angled arms that ended in spatulate swellings. The lobed pommels on earlier swords were inspired by the Viking style. The spatulate swellings were later frequently made in a quatrefoil design.
The average claymore ran about 140 cm (55 in) in overall length, with a 33 cm (13 in) grip, 107 cm (42 in) blade, and a weight of approximately 5.5 lb (2.5 kg). For instance, in 1772 Thomas Pennant described a sword seen on his visit to Raasay as: "an unwieldy weapon, two inches broad, doubly edged; the length of the blade three feet seven inches; of the handle, fourteen inches; of a plain transverse guard, one foot; the weight six pounds and a half." The largest claymore on record; known as Fuilteach Mhuirt "blooded/bloody one of murder/killing", weighs 10 kilograms and measures 2.24 metres in length. It is believed to have been wielded by a member of Clan Maxwell circa the 15th century. The sword is currently in the possession of the National War Museum in Edinburgh, Scotland.
Fairly uniform in style, the sword was set with a wheel pommel often capped by a crescent-shaped nut and a guard with straight, forward-sloping arms ending in quatrefoils, and langets running down the centre of the blade from the guard. Another common style of two-handed claymore (though lesser known today) was the "clamshell hilted" claymore. It had a crossguard that consisted of two downward-curving arms and two large, round, concave plates that protected the foregrip. It was so named because the round guards resembled an open clam.
