A flatbow is a bow with non-recurved, flat, relatively wide limbs that are approximately rectangular in cross-section. Because the limbs are relatively wide, flatbows will usually narrow and become deeper at the handle, with a rounded, non-bending handle for easier grip. This design differs from that of a longbow, which has rounded limbs that are circular or D-shaped in cross-section, and is usually widest at the handle. A flatbow can be just as long as a longbow, but can also be very short. Typical lengths would be 68–70 inches (172.5–178 cm) for a flatbow, 70–72 inches (178–183 cm) for an English longbow, and 72–76 inches (183–193 cm) for a warbow-weight English longbow; but these styles may easily overlap each other. Traditional flatbows are usually wooden self bows (bows made of one solid piece of wood), though laminated and composite flatbows have been made in ancient and modern times. Modern flatbows commonly use fiberglass.

Advantages of a rectangular cross-section

The flatbow is a superior bow design for almost all materials because the stress is more evenly spread out than with rounded limb sections. A bow limb is essentially a flexed beam undergoing bending, and in any flexed beam the farther from the neutral axis (line in the middle of the flexing beam which is not under tension or compression: see diagram in Bending article) the more stress there is within the material. When a limb is rounded, as in a longbow, some material sticks out farther from the neutral axis, and thus is put under greater stress. In a flatbow, the flat belly and back ensure that all of the most strained material is a uniform distance from the neutral axis, spreading the load over a wider limb, minimizing stress and making weaker woods far less likely to fail (break or become permanently bent and lose the resilience needed in a bow). Only particularly resilient timbers can make an effective and powerful wooden longbow.

Suitable timbers

In most parts of the world, common hardwoods may be used to create excellent bows. Suitable and easily available timbers include elm (used in ancient Europe, as evidenced by bows pulled from European bogs), maple, sycamore, hazel, and ash. The flatbow design also lends itself to very dense, high strength woods such as hickory and especially osage orange (a wood favored by many Native American tribes for bow making).

Disadvantages of a rectangular cross-section

Compared with a narrow, rounded longbow design, the bowyer needs to start with a wider stave, take more time to achieve an approximately rectangular cross-section, and may need to cut through growth rings on the back of the bow.[ citation needed ]

Historic use

Flatbows were used by Native American tribes such as the Hupa, Karok, and Wampanoag, prehistoric ancient Europeans, some Inuit tribes, Finno-Ugric nations and a number of other pre-gunpowder societies for hunting and warfare because, unlike longbows, good flatbows can be made from a wide variety of timbers. Flatbows fell from favour in Europe after the Mesolithic, replaced with yew longbows.[ citation needed ] The trade of yew wood for English longbows was such that it depleted the stocks of yew over a huge area. [1] Flatbows are currently used by the Sentinelese tribes of the Andaman Islands. Flatbows survived in cold areas, such as Finland, where yew does not grow naturally because of the unsuitable climate. The traditional Finnish flatbow is made either from ash, or as birch/pine laminate with siyahs made of hagberry and glued together with glue, made by cooking descaled skins of perch with minimum amount of water, until one will get a solution like thick, slimy, grey porridge. This kind of glue will never be all waterproof and the bows were most often wrapped with thin strips of birch bark, protecting them against weather and moisture. Yew was available as an imported material (it grows in Southern Sweden and Denmark and it was even cultivated there) for bows in Finland, but it was considered not suitable for serious use, because it is fragile at cold temperatures and the season for hunting for furs is in January and February, when the furs are at their best.[ citation needed ]

American longbow

The American longbow, also known as the American semi-longbow (ASL), and sometimes incorrectly called the American flatbow (see above for the correct definition of flatbow), was developed in the 1930s. It resulted from scientific investigation into the best cross-sectional shape for a bow limb. This research was expected to explain why the English longbow's D-section was superior to all other extant designs. Instead, it showed that the best cross-section was a simple rectangle. [2] The American longbow was developed by applying these research findings to the English longbow. The result was a more efficient and stable bow which can be made from more common woods.

One of the primary differences between an American longbow and a flatbow - is that the flatbow has wide limbs and a narrow handle section. [3] [4] The American longbow has narrow limbs and a handle that is of similar width.

The American longbow was popularised by Howard Hill and quickly displaced the English longbow as the preferred bow for target shooting at the time. Howard himself referred to it as a semi-longbow. [5] It was not long before Howard started to use fiberglass on the back and belly of his bows. Consequently, the ASL is sometimes referred to as a Hill style bow.

The American Longbow is not to be confused with what is now marketed as a modern longbow or hybrid longbow which is just modern marketing pseudo term for what was called a semi-recurve prior to the 90's. IFFA (The International Field Archery Association) does not recognize the modern or hybrid longbow as a longbow, [6] and hence these are shot in recurve divisions. [7]

Archery is the sport, practice, or skill of using a bow to shoot arrows. The word comes from the Latin arcus, meaning bow. Historically, archery has been used for hunting and combat. In modern times, it is mainly a competitive sport and recreational activity. A person who practices archery is typically called an archer, bowman, or toxophilite.

<span class="mw-page-title-main">English longbow</span> Type of ranged weapon

The English longbow was a powerful medieval type of bow, about 6 ft (1.8 m) long. While it is debated whether it originated in England or in Wales from the Welsh bow, by the 14th century the longbow was being used by both the English and the Welsh as a weapon of war and for hunting. English longbows were effective against the French during the Hundred Years' War, particularly in the battles of Sluys (1340), Crécy (1346), Poitiers (1356), and Agincourt (1415). They were less successful later on, as longbowmen had their lines broken at the Battle of Verneuil (1424), although the English won a decisive victory there; they were completely routed at the Battle of Patay (1429) when they were charged by the French mounted men-at-arms before they had prepared the terrain and finished defensive arrangements. The Battle of Pontvallain (1370) had also previously shown longbowmen were not particularly effective when not given the time to set up defensive positions.

An arrow is a fin-stabilized projectile launched by a bow. A typical arrow usually consists of a long, stiff, straight shaft with a weighty arrowhead attached to the front end, multiple fin-like stabilizers called fletchings mounted near the rear, and a slot at the rear end called a nock for engaging the bowstring. A container or bag carrying additional arrows for convenient reloading is called a quiver.

<span class="mw-page-title-main">Compound bow</span> Type of bow for archery

In modern archery, a compound bow is a bow that uses a levering system, usually of cables and pulleys, to bend the limbs. The compound bow was first developed in 1966 by Holless Wilbur Allen in North Kansas City, Missouri, and a US patent was granted in 1969. Compound bows are widely used in target practice and hunting.

<span class="mw-page-title-main">Bow and arrow</span> Pre-gunpowder ranged weapon system

The bow and arrow is a ranged weapon system consisting of an elastic launching device (bow) and long-shafted projectiles (arrows). Humans used bows and arrows for hunting and aggression long before recorded history, and the practice was common to many prehistoric cultures. They were important weapons of war from ancient history until the early modern period, where they were rendered increasingly obsolete by the development of the more powerful and accurate firearms. Today, bows and arrows are mostly used for hunting and sports.

<span class="mw-page-title-main">Bow shape</span> Important aspect of archery

In archery, the shape of the bow is usually taken to be the view from the side. It is the product of the complex relationship of material stresses, designed by a bowyer. This shape, viewing the limbs, is designed to take into account the construction materials, the performance required, and the intended use of the bow.

<span class="mw-page-title-main">Composite bow</span> Bow made from horn, wood, and sinew laminated together

A composite bow is a traditional bow made from horn, wood, and sinew laminated together, a form of laminated bow. The horn is on the belly, facing the archer, and sinew on the outer side of a wooden core. When the bow is drawn, the sinew and horn store more energy than wood for the same length of bow. The strength can be made similar to that of all-wood "self" bows, with similar draw-length and therefore a similar amount of energy delivered to the arrow from a much shorter bow. However, making a composite bow requires more varieties of material than a self bow, its construction takes much more time, and the finished bow is more sensitive to moisture.

<span class="mw-page-title-main">Bowyer</span> History of the trade of bowmaking

A bowyer is a master-craftsman who makes bows. Though this was once a widespread profession, the importance of bowyers and of bows was diminished by the introduction of gunpowder weaponry. However, the trade has survived and many bowyers continue to produce high-end bows.

A longbow is a type of tall bow that makes a fairly long draw possible. A longbow is not significantly recurved. Its limbs are relatively narrow and are circular or D-shaped in cross section. Flatbows can be just as long, but in cross-section, a flatbow has limbs that are approximately rectangular.

<span class="mw-page-title-main">History of archery</span> Aspect of history

Archery, or the use of bow and arrows, was probably developed in Africa by the later Middle Stone Age. It is documented as part of warfare and hunting from the classical period until the end of the 19th century, when it was made obsolete by the invention and spread of repeating firearms.

<span class="mw-page-title-main">Self bow</span> Type of archery bow

A self bow or simple bow is a bow made from a single piece of wood. Extra material such as horn nocks on the ends, or built-up handles, would normally be accepted as part of a self bow. Some modern authorities would also accept a bow spliced together in the handle from two pieces of wood.

A laminated bow is an archery bow in which different materials are laminated together to form the bow stave itself. Traditional composite bows are normally not included, although their construction with horn, wood, and sinew might bring them within the above definition.

<span class="mw-page-title-main">Bowstring</span> String joining the two ends of a bow stave

A bowstring joins the two ends of the bow stave and launches the arrow. Desirable properties include light weight, strength, resistance to abrasion, and resistance to water. Mass has most effect at the center of the string; one gram (0.035 oz) of extra mass in the middle of the string slows the arrow about as much as 3.5 grams (0.12 oz) at the ends.

<span class="mw-page-title-main">Cable-backed bow</span> Type of ranged weapon

A cable-backed bow is a bow reinforced with a cable on the back. The cable is made from either animal, vegetable or synthetic fibers and is tightened to increase the strength of the bow. A cable will relieve tension stress from the back of the bow by raising its neutral plane: the border between the back of the bow that stretches and the belly of the bow that compresses when bent. A good cable-backed bow can thus be made of poor-quality wood, weak in tension. The material, the diameter, the distance from the back of the wooden element, and the level of stress (tightness) of the cable determines how much it relieves tension stress from the wooden element of the bow and increases the power of the shot.

<span class="mw-page-title-main">Recurve bow</span> Type of bow shape in archery

In archery, a recurve bow is one of the main shapes a bow can take, with limbs that curve away from the archer when unstrung. A recurve bow stores more energy and delivers energy more efficiently than the equivalent straight-limbed bow, giving a greater amount of energy and speed to the arrow. A recurve will permit a shorter bow than the simple straight limb bow for given arrow energy, and this form was often preferred by archers in environments where long weapons could be cumbersome, such as in brush and forest terrain, or while on horseback.

The Holmegaard bows are a series of self bows found in the bogs of Northern Europe dating from the Neolithic period. They are named after the Holmegaard area of Denmark in which the first and oldest specimens were found, and are the oldest bows discovered anywhere in the world.

Traditional Inuit hunters lack the more elastic timbers used to make bows in temperate and tropical parts of the world. Using sinew cords for the back of the bow, and spruce timber or antler for the belly, however, they build very effective weapons. When hunting polar bears, the bows used are powerful enough, if they do not hit bone, to penetrate completely through the body of the bear.
