The blade is made of non-rustproof carbon steel, blue-plastered by hand and finely forged from the base to the tip of the knife. The 90 mm (3.5 in) long blade shows patina (dark spots) caused by decades of use. It can easily be sharpened to a shaving sharp edge. Carbon steel is a popular choice for rough-use knives and cheaper options.
Swords made of iron (as opposed to bronze) appear from the Early Iron Age (c. 12th century BC), [citation needed] but do not become widespread before the 8th century BC. Early Iron Age swords were significantly different from later steel swords. They were work-hardened, rather than quench-hardened, which made them about the same or only ...
The weight of an average sword of 70 cm (28 in) blade-length would weigh about 700 to 900 g (1.5 to 2.0 lb). [20] There are also larger two-handed versions used by ancient and medieval armies and for training by many styles of Chinese martial arts. Two handed jians from the time of the Chu and Han dynasty were up to 58 in (150 cm) long.
Dedicated cutting blades are wide and thin, and often have grooves known as fullers which lighten the blade at the cost of some of the blade's stiffness. The edges of a cutting sword are almost parallel. Blades oriented for the thrust have thicker blades, sometimes with a distinct midrib for increased stiffness, with a strong taper and an acute ...
The Ulfberht swords are a group of about 170 medieval swords found primarily in Northern Europe, [3] [4] dated to the 9th to 11th centuries, with blades inlaid with the inscription +VLFBERH+T or +VLFBERHT+. [3] [5] The word "Ulfberht" is a Frankish personal name, possibly indicating the origin of the blades.
This allows the sword to have the strength and the ability to hold a sharp edge, as well as to cause the sword to tend to bend rather than flex under stress. The process starts in the combining of the iron and carbon, by heating iron sand to 1200-1500 degrees Celsius in a traditional furnace, or tatara, for 72 hours.
A longsword (also spelled as long sword or long-sword) is a type of European sword characterized as having a cruciform hilt with a grip for primarily two-handed use (around 15 to 30 cm or 6 to 12 in), a straight double-edged blade of around 80 to 110 cm (31 to 43 in), and weighing approximately 2 to 3 kg (4 lb 7 oz to 6 lb 10 oz).
Bone awls are pointed tips made on any bone splinter. Bone awls vary considerably in the amount of polish from wear, the method of preparation, and size. Bone awls tend to be classified according to the characteristics of the bone used to make the awl. Many bone awls retain an epiphysis, or rounded end of a bone. Although authors have differing ...
