Title: Hairpin turn
Content:   A hairpin turn (also hairpin bend or hairpin corner) is a bend in a road with a very acute inner angle, making it necessary for an oncoming vehicle to turn about 180° to continue on the road. It is named for its resemblance to a bent metal hairpin. Such turns in ramps and trails may be called switchbacks in American English, by analogy with switchback railways. In British English "switchback" is more likely to refer to a heavily undulating road—a use extended from the rollercoaster and the other type of switchback railway.
Title: Anchor bend
Content:  Its name originates from the time when "bend" was understood to simply mean "tie to"; today, a bend strictly refers to a knot that joins two lines.
Title: Anchor bend
Content:  The anchor bend is a knot used for attaching a rope to a ring or similar termination. The name is a misnomer, as it is technically not a bend, but a hitch.
Title: Bend (heraldry)
Content:  The phrase in bend refers to the appearance of several items on the shield being lined up in the direction of a bend, as in the arms of the ancient Northcote family of Devon: Argent, three crosses-crosslet in bend sable. It is also used when something is slanted in the direction of a bend, as in the coat of Surrey County Council in England.
Title: Zeppelin bend
Content:  in contrast to the rigger's bend (AKA Hunter's bend, #1425A) which is formed from two inter-linked loops of the same chirality. Chirality refers to the "handedness" of the loop, which can be either "S" (left) or "Z" (right). The chirality of a loop cannot be changed by flipping or turning it over &ndash; in the same way, a left shoe cannot be transformed into a right shoe by flipping or turning it over (it is always a left shoe). The Zeppelin bend is difficult to tie while ropes are under tension (which is further obvious evidence that it wasn't used with mooring 
Title: Hunter's bend
Content:  Hunter's bend (or rigger's bend) is a knot used to join two lines. It consists of interlocking overhand knots, and can jam under moderate strain. It is topologically similar to the Zeppelin bend. When assessed against other bends in stress tests using paracord, it was found to be "not as strong as the blood knot, similar to the reverse figure of eight and stronger than the fisherman's bend, sheet bend or reef knot".
Title: Hairpin turn
Content:  If a railway curves back on itself like a hairpin turn, it is called a horseshoe curve. The Pennsylvania Railroad  built one in Blair County, Pennsylvania ascending the Eastern Continental Divide from the east. However, the radius of curvature is much larger than that of a typical road hairpin. See this example at Zlatoust or Hillclimbing for other railway ascent methods.
Title: Ashley's bend
Content:  Ashley's bend is a knot used to securely join the ends of two ropes together. It is similar to several related bend knots which consist of two interlocking overhand knots, and in particular the alpine butterfly bend. These related bends differ by the way the two constituent overhand knots are interlocked.
Title: Hairpin
Content:  the invention of the spiral hairpin by New Zealand inventor Ernest Godward. This was a predecessor of the hair clip. The hairpin may be decorative and encrusted with jewels and ornaments, or it may be utilitarian, and designed to be almost invisible while holding a hairstyle in place. Some hairpins are a single straight pin, but modern versions are more likely to be constructed from different lengths of wire that are bent in half with a u-shaped end and a few kinks along the two opposite portions. The finished pin may vary from two to six inches in last length. The length of the wires enables placement in several designs of hairstyles to hold the nature in place. The kinks enable retaining the pin during normal movements. A hairpin patent was issued to Kelly Chamandy in 1925.
Title: Zeppelin bend
Content:  A Zeppelin bend (also known as the Rosendahl Bend) is an end-to-end joining knot formed by two symmetrically interlinked overhand knots. It is stable, secure, and highly resistant to jamming. It is also resistant to the effects of slack shaking and cyclic loading.
