Often one of the beads is fixed, either via [[epoxy]] or [[welding]], so that only one bead is used to install or remove the [[jewelry]]. Barbell [[screw thread|threads]] are usually right-handed. They are named because they resemble the [[barbell]]s that are used in [[weightlifting]]. ==Types of barbells== '''Internally threaded barbells''', so named because the bar has smooth ends with receiving threads tapped into the end of the bar. In internally threaded jewelry, the bead has a receiving tube machined into it (this is referred to as "countersunk"), with a threaded post extending from the center, which mates with the threaded receiving tube on the bar. Being much less likely to cause damage and irritation, especially at the time of piercing, internally threaded jewelry is considered superior to externally threaded jewelry. It is usually slightly more expensive than externally threaded jewelry, due to the extra machining and labor involved. '''Externally threaded barbells''', so named because the shaft of the bar has threads at both ends to allow beads with receiving threads to be attached. Due to the potential damage or irritation to the piercing when the threads pass through when the jewellery is inserted or removed, this type of barbell has become less common, due to the popularity of the internally threaded barbell. This type of barbell is usually only used when the [[Stretching (body piercing)|gauge]] of the bar is too small to allow it to be internally threaded, or in cheap, mass produced body jewelry. Some higher-end manufacturers make externally threaded barbells with "step-down threading", where the threaded section has a smaller diameter than the wearable section; these are fairly uncommon and usually internally threaded barbells are used in their place. Step-down threaded jewelry ends can be inserted into the blunt end of a hollow piercing needle, allowing for less irritation during initial placement than regular external barbells or even internally threaded barbells. '''Curved barbells''' (also known as a ''navel curve'' or ''curve''), so named because of their [[curvature]]. A curved barbell is mechanically identical to a straight barbell, except for being curved. Curvature on a curved barbell can range from almost straight to [[circular]], with some barbells actually being [[spiral]], with the ends overlapping but separated to allow the insertion of the jewelry. A variation on this design is a J-bar, a slightly curved barbell (sometimes referred to as a ''bananabell'' or ''banana barbell'') with a 90 degree bend near one end, used in vertical [[navel piercing]]s to position the decorative end of the jewelry more appropriately. They can be either internally threaded or externally threaded. '''Surface bars''', used in [[surface piercing]]s. A surface bar is a barbell where the bar has a pair of 90 degree bends, in the same direction (similar to a [[Staple (fastener)|staple]]), to allow the jewelry to be used for surface piercings. This design minimizes the pressure that would be caused by other jewelry designs that contributes to [[piercing migration|rejection]] in healing surface piercings. Most surface bars are custom made to fit the individual piercing. '''Circular barbells''' are also know as a [[horseshoe]] barbells due to their shape, resembling the latest in [[equine]] footwear. They are used in any number of [[body piercing|piercing]]s, including earrings, [[Tragus piercing|tragus]] rings, nasal [[septum]] piercings, [[Madison piercing|madisons]], or even horizontal [[clitoral hood]] piercings, although the latter is less common, as the clitoris is deprived of the stimulation gained from a properly positioned [[captive bead ring]]. ==Types of beads== Beads for barbells can vary widely in design and appearance, although the vast majority of beads are simply [[spherical]] in design. That being said, any shape that threads can be tapped into can be used as a bead. [[Cube]]s, [[triangle]]s, [[cylinder (geometry)|cylinder]]s, [[cone (geometry)|cone]]s, [[Disk (mathematics)|disks]], and other basic shapes are common alternative bead designs. Some large gauge barbells, especially those used in [[tongue piercing]]s, use "smartie beads", flattened circular beads, to prevent the jewelry from damaging the gums and teeth and allowing free movement of the [[tongue]]. There also exist "bondage" beads, which are dimpled to accept a [[captive bead ring]]. ==Materials== Barbell style jewelry can and is made from any metal appropriate for making [[body jewelry materials|body jewelry]]. Flexible barbells made from [[Teflon]] or [[tygon]] tubing are often used in experimental surface or deep tissue piercings. Beads do not penetrate the body, so often materials not usually considered safe for piercing can be used in a decorative manner such as [[Polymethyl methacrylate|acrylic]], [[glass]], or organic materials. ==History and culture== Although at first glance the manufacture of threaded jewelry might appear to be of contemporary origin, there are examples of externally threaded, straight barbells being used by [[Tribe|tribal]] people, most notably the [[Dayak]] of [[Borneo]]. In contemporary society, barbell style jewelry was popularized by [[Jim Ward (body piercing)|Jim Ward]], founder of [[Gauntlet (body piercing studio)|Gauntlet]] (the first [[body piercing]] studio in the [[United States]]), in the 1970s. He was introduced to barbell style jewelry by Tattoo Samy, a tattooist and piercer from [[Frankfurt]], [[Germany]]. {{Fact|date=February 2007}} Jim Ward’s name is synonymous with the origins of western body piercing. His magazine [[PFIQ]] is also just as phenomenal and historic in name. PFIQ shows the early roots of body piercing. Tygon is a registered trademark of the Saint-Gobain Corporation.
