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.
This bow form reduces the strain on the limbs and also the energy stored by the weapon. Most modern recurve bows are built with some degree of deflex. It has been used occasionally in traditional bows, for example to make a bow that looks like a traditional hornbow without using any actual horn.
For example, a 27 kg (60 lb) bow with 80% let-off only requires 53 N (12 lb f) to hold at full draw. Up to 99% let-off is possible. [54] The compound bow was invented by Holless Wilbur Allen in the 1960s (a US patent was filed in 1966 and granted in 1969) and it has become the most widely used type of bow for all forms of archery in North America.
An example of this type of bow is the Genesis, which is standard equipment in the U.S. National Archery in the Schools Program. Compound bow strings and cables are normally made of high-modulus polyethylene and are designed to have great tensile strength and minimal stretchability, so that the bow transfers its energy to the arrow as ...
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 profound bow is a deep bow from the waist, and is often done as a substitution for genuflection. In Eastern Orthodoxy, there are several degrees of bowing, each with a different meaning. Strict rules exist as to which type of a bow should be used at any particular time. The rules are complicated and are not always carried out in all parishes.

Estimates for the draw of these bows varies considerably. Before the recovery of the Mary Rose, Count M. Mildmay Stayner, Recorder of the British Long Bow Society, estimated the bows of the Medieval period drew 90–110 pounds-force (400–490 newtons), maximum, and W. F. Paterson, Chairman of the Society of Archer-Antiquaries, believed the weapon had a supreme draw weight of only 80–90 lb f ...
