A silver Peruvian atlatl from the 12th-15th century Atlatl in use. A spear-thrower, spear-throwing lever, or atlatl (pronounced / ˈ æ t l æ t əl / ⓘ [1] or / ˈ ɑː t l ɑː t əl /; [2] Nahuatl ahtlatl [ˈaʔt͡ɬat͡ɬ]) is a tool that uses leverage to achieve greater velocity in dart or javelin-throwing, and includes a bearing surface that allows the user to store energy during the ...
Unlike other projectile weapons, the atlatl could throw projectiles with greater force and accuracy than could be achieved by hand. In addition to harpoon-tipped spears, California Natives in the coasts also used a variety of other projectile weapons for hunting fish, including bows and arrows.
A Swiss arrow [1] (also known as a Yorkshire arrow, Dutch arrow, Scotch arrow, or Gypsy arrow) is a type of enlarged dart in the shape of an arrow that is thrown with the aid of a lanyard, which is retained by a small notch close to the fletching. It is very similar to an amentum and uses the same throwing principle as a spear-thrower.
Arrow points are smaller and lighter than dart points, and were used to tip arrows. The question of how to distinguish an arrow point from a point used on a larger projectile is non-trivial. According to some investigators, the best indication is the width of the hafting area, which is thought to correlate to the width of the shaft. [ 4 ]
Later suggestions arose that the points had been used as throwing spears, either as is or with spear thrower (atlatl) which technically would be considered darts, or as a braced weapon . [6] [7] [8] It is also possible the points were used in the animal butchering process. [9] Folsom point for comparison
Also amphidrome and tidal node. A geographical location where there is little or no tide, i.e. where the tidal amplitude is zero or nearly zero because the height of sea level does not change appreciably over time (meaning there is no high tide or low tide), and around which a tidal crest circulates once per tidal period (approximately every 12 hours). Tidal amplitude increases, though not ...
Depending on your height, you'll want to use a dart that's about a foot taller than you are for better accuracy. Using an atlatl can be easy. Hitting a target is another story.
Stability in flight was important because it allowed the javelin to land on its point, which was the only way the throw could be accurately recorded in competition or be useful against a live target. An amentum also increased the effective length of the throwing arm, as does a spear-thrower, so enhanced speed. It is very similar to the Swiss arrow.
