24-534: The badik consists of three parts, namely the handle and blade, as well as the sheath or scabbard. It comes in a great variety of shapes and sizes. The badik can have a straight, curved, bulbous or wavy, single- or double-edged blade. The blade is smooth or with hollow sections ( fullered ). The point of the blade can be either pointed or rounded. Like the kris , the shape of the blade is asymmetric and often shows patterns typical of pamor ( pattern welding steel commonly known as Damascus steel ). However, it differs from

48-401: A sword , knife , or bayonet ) that serves to both lighten and stiffen the blade, when considering its reduced weight. Cutting or grinding a fuller into an existing blade will decrease its absolute stiffness due to the removal of material, but much of the strength remains due to the geometry of its shape. When the groove is forged into the blade, it achieves a similar reduction in weight with

72-507: A 22-degree angle. While it is not possible to create a complete and functional die with the bevel material of a wafer, the area is still routinely processed throughout the manufacturing cycle to remove unwanted masks, residues, and films from the edge of a wafer that could potentially become a source of defects between manufacturing steps. Beveling and chamfering (along with other profiles) are applied to thicker pieces of metal prior to welding, see Welding joint#V-joints . The bevel provides

96-420: A bevelled edge which is apparent when one examines the grind . Bevel angles can be duplicated using a sliding T bevel . Typographic bevels are shading and artificial shadows that emulate the appearance of a 3-dimensional letter. The bevel is a relatively common effect in graphic editors such as Photoshop . As such, it is in widespread use in mainstream logos and other design elements. Bevelled edges are

120-482: A common aesthetic nicety added to window panes and mirrors. Geologists refer to any slope of land into a stratum of different elevation as a bevel. In waterskiing, a bevel is the transition area between the side of the ski and the bottom of the ski. Beginners tend to prefer sharp bevels, which allow the ski to glide on the water surface. In Disc Golf , the 'beveled edge' was patented in 1983 by Dave Dunipace who founded Innova Champion Discs. This element transformed

144-419: A groove is to be applied to both sides of the steel, two fullers may be used at the same time, sandwiching the workpiece in the middle. Often, one fuller will have a peg that holds it securely in the anvil , while the other fuller will have a handle and a flat head, for striking with a hammer. A blade being fullered will generally be slowly pulled through the fullers as it is being hammered, displacing material to

168-400: A long bar, fullers are also used in the production of items such as hinges and latches, plow parts, and horseshoes. In Japanese swordsmithing , fullers have a rich tradition and terminology, enough that there are separate terminologies for the top ( hi , usually pronounced as bi when used as the second member of a compound) and bottom ( tome ) ends of the feature. The Nepali kukri has

192-407: A relatively small reduction in strength without the wasted material produced by grinding. When impressed during forging, it may be made using a blacksmithing tool that is also called a fuller, a form of spring swage. When combined with optimal distal tapers , heat treatment and blade tempering, a fullered blade can be 20% to 35% lighter than a non-fullered blade. The ridges and groove created by

216-479: A smooth clean edge to the plate or pipe and allows a weld of the correct shape (to prevent center-line cracking) to join the separate pieces of metal. Simple bevels can be used with a backup strip (thin removable sheet behind the plate joint) with chamfers (and a small land) being used on open root welds. Particularly thick plate will have a J-shaped chamfer or U-shaped groove to reduce the amount of welding filler metal used. Cruciform joint preparation can involve

240-468: A terminology of its own, including the "aunlo bal" (finger of strength/force/energy), a relatively deep and narrow fuller near the spine of the blade, which runs (at most) between the handle and the corner of the blade, and the "chirra", which may refer either to shallow fullers in the belly of the blade or a hollow grind of the edge, and of which two or three may be used on each side of the blade. Bevel A bevelled edge (UK) or beveled edge (US)

264-459: A weapon and hunting tool, the badik is a symbol of cultural identity in Sulawesi. In the colonial era, it was considered a pity if a man died without his badik. As recently as the 1960s, the badik was worn as part of daily attire and badik crimes were reported regularly. The Bugis and Makassar people still carry badik on ceremonial occasions today. The badik is worn on the right side, butt end of

288-449: Is an edge of a structure that is not perpendicular to the faces of the piece. The words bevel and chamfer overlap in usage; in general usage, they are often interchanged, while in technical usage, they may be differentiated as shown in the image on the right. A bevel is typically used to soften the edge of a piece for the sake of safety, wear resistance, aesthetics ; or to facilitate mating with another piece. Most cutting tools have

312-504: Is brought into action from the intended victim's side or rear. The Draw is made across the operator's body by slashing from left to right; the blade may be "feathered" (turned over) and another slash from the right to the left, but only if the first one fails to do the job. But it is the thrust which the Bugis and Makassarese rely most heavily upon. The blade of the Bugis badik is thinner than that of

336-575: Is from the Old English fuliere , meaning 'one that fulls [pleats] cloth'. It is derived from the Latin word fullo . The first recorded use of the term in relation to metal working is 1587. The first recorded use of the term to describe a groove or channel in a blade is 1967. As a blacksmithing tool, a fuller is a type of swage , a tool with a cylindrical or beveled face used to imprint grooves into metal. Fullers are typically three to six inches long. If

360-668: The Malay Peninsula , creating a wide variety of badik styles according to each region and ethnic group. There are many versions made and used throughout the Indonesian archipelago alone. As with other blades in the Malay Archipelago, traditionally-made badik are believed to be imbued with a supernatural force during the time of their forging. The pamor in particular is said to affect its owner, bringing either well-being and prosperity or misfortune and poverty. Aside from being used as

384-543: The Banyorangese community) in which the duellists fight in a sarong . The challenger stands with a loosened sarong around him and respectfully invites the other man to step into the sarong. The sarong itself is kept taut around both their waists. When both men are inside, an agreement to fight til death and thereafter shall be no hereditary grudge nor will any party be allowed to question the duel, shall be made. If both fighters agree, they then engage each other with badik within

408-472: The Frisbee into the further-flying golf discs the sport uses today. With a deck of cards, the top portion can be slid back so that the back of the deck is at an angle, a technique used in card tricks . In the semiconductor industry , wafers have two typical edge types: a slanted beveled shape or a rounded bullet shape. The edges on the beveled types are called the bevel region, and they are typically ground at

432-521: The Makassarese type. The latter, therefore, must be thrust with its blade flat if lethal penetration is to be achieved in rib areas; other areas of the victim's anatomy do not require this repositioning, but the Makassarese generally use the flat-blade tactic, and seek full penetration of the blade. The Bugis on the other hand, pinch the blade more often than do the Makassarese, with the fingers just below

456-443: The confined space of a single sarong. Because avoiding injury is near-impossible even for the victor, this type of duel was considered a sign of extraordinary bravery, masculinity and the warrior mentality. Although true sitobo lalang lipa are no longer practiced, enactments of these duels are still performed at cultural shows today. The badik is the main weapon in Bugis and Mangkasara styles of pencak silat . The Badik almost always

480-410: The fuller are comparable to an I-beam's flanges and web; this shape aims to optimize the strength and stiffness for a given quantity of material, particularly in the cutting direction. A fuller is often used to widen a blade during smithing or forging. Fullers are sometimes inaccurately called blood grooves or blood gutters . Channelling blood is not the purpose of a fuller. The term "fuller"

504-507: The handle pointing to the rear; it may also be positioned at their left side providing the butt end of the handle points to the rear. When the weapon is shifted from the right to the left side, or when worn at the left, handle reversed facing forward, it is signatory of impending combat. The traditional form of duelling among the Bugis - Makassar community was called sigajang laleng lipa (in Bugis language ), sitobo lalang lipa (in Makassarese language ) or sibajji lalang lipa (among

528-438: The kris in that the badik does not have a ganja (a buffer strip steel). Some versions from Sulawesi are decorated with inlaid gold figure on the blade called jeko . The handle is made of wood, horn or ivory in a shape of a pistol grip at a 45° to 90° angle or similar in a bent shape often decorated with carvings. From its native Sulawesi, the badik soon spread to neighbouring islands like Java , Borneo , Sumatra and as far as

552-411: The place where the handle joins the blade. And the thrust may be brought to penetration in a vertical or flat entry, to the depth of the pinch grip. Lethal penetration in selected vital anatomical targets can be surely made with less than 3 in (76 mm) of the blade Fuller (weapon) A fuller is a rounded or beveled longitudinal groove or slot along the flat side of a blade (e.g.,

576-410: The side (rather than removing it) and thereby creating ridges on either side of a groove. These ridges may be hammered flat, widening the blade, or they are often shaped with other swages, increasing the strength of the blade both by creating thicker areas in its cross section and lateral ridges that resist lengthwise deflection. In addition to being used to "draw out" steel, hammering a short block into
