Blade in the context of "Hilt"

A knife (pl.: knives; from Old Norse knifr 'knife, dirk') is a tool or weapon with a cutting edge or blade, usually attached to a handle or hilt. One of the earliest tools used by humanity, knives appeared at least 2.5 million years ago, as evidenced by the Oldowan tools. Originally made of wood, bone, and stone (such as flint and obsidian), over the centuries, in step with improvements in both metallurgy and manufacturing, knife blades have been made from copper, bronze, iron, steel, ceramic, and titanium. Most modern knives have fixed or folding blades, with styles varying by maker and country.

Knives can serve various purposes. Hunters use a hunting knife, soldiers use the combat knife, scouts, campers, and hikers carry a pocketknife; there are kitchen knives for preparing foods (the chef's knife, the paring knife, bread knife, cleaver), table knife (butter knives and steak knives), weapons (daggers or switchblades), knives for throwing or juggling, and knives for religious ceremony or display (the kirpan).

A dagger is a fighting knife with a very sharp point and usually one or two sharp edges, typically designed or capable of being used as a cutting or thrusting weapon. Daggers have been used throughout human history for close combat confrontations, and many cultures have used adorned daggers in ritual and ceremonial contexts. The dagger's distinctive shape and historic usage have made it iconic and symbolic. In the modern sense, a dagger is designed for close-proximity combat or self-defense; due to its use in historic weapon assemblages, it has associations with assassination and murder. However, double-edged knives play different roles in different social contexts.

A wide variety of thrusting knives have been described as daggers, including knives that feature only a single cutting edge, such as the European rondel dagger or the Afghan pesh-kabz, or, in some instances, no cutting edge at all, such as the stiletto of the Renaissance. However, in the last hundred years or so, in most contexts, a dagger has specific definable characteristics, including a short blade with a sharply tapered point, a central spine or fuller, and usually two cutting edges sharpened the entire length of the blade, or nearly so. Most daggers also feature a full crossguard to keep the hand from riding forwards onto the sharpened blade edges.

A sickle, bagging hook, reaping-hook or grasshook is a single-handed agricultural tool designed with variously curved blades and typically used for harvesting or reaping grain crops, or cutting succulent forage chiefly for feeding livestock. Falx was a synonym, but was later used to mean any of a number of tools that had a curved blade that was sharp on the inside edge.

Since the beginning of the Iron Age hundreds of region-specific variants of the sickle have evolved, initially of iron and later steel. This great diversity of sickle types across many cultures can be divided into smooth or serrated blades, both of which can be used for cutting either green grass or mature cereals using slightly different techniques. The serrated blade that originated in prehistoric sickles still dominates in the reaping of grain and is even found in modern grain-harvesting machines and in some kitchen knives.

A water wheel is a machine for converting the kinetic energy of flowing or falling water into useful forms of power, often in a watermill. A water wheel consists of a large wheel (usually constructed from wood or metal), with numerous blades or buckets attached to the outer rim forming the drive mechanism. Water wheels were still in commercial use well into the 20th century, although they are no longer in common use today. Water wheels are used for milling flour in gristmills, grinding wood into pulp for papermaking, hammering wrought iron, machining, ore crushing and pounding fibre for use in the manufacture of cloth.

Some water wheels are fed by water from a mill pond, which is formed when a flowing stream is dammed. A channel for the water flowing to or from a water wheel is called a mill race. The race bringing water from the mill pond to the water wheel is a headrace; the one carrying water after it has left the wheel is commonly referred to as a tailrace.

A shovel is a tool used for digging, lifting, and moving bulk materials, such as soil, coal, gravel, snow, sand, or ore. Most shovels are hand tools consisting of a broad blade fixed to a medium-length handle. Shovel blades are usually made of sheet steel or hard plastics and are very strong. Shovel handles are usually made of wood (especially specific varieties such as ash or maple) or glass-reinforced plastic (fiberglass).

Hand shovel blades made of sheet steel usually have a folded seam or hem at the back to make a socket for the handle. This fold also commonly provides extra rigidity to the blade. The handles are usually riveted in place. A T-piece is commonly fitted to the end of the handle to aid grip and control where the shovel is designed for moving soil and heavy materials. These designs can all be easily mass-produced.

A machete (/məˈʃɛti/; Spanish pronunciation: [maˈtʃete]) is a broad blade originating from Central America, It used either as an agricultural implement similar to an axe, or in combat like a long-bladed knife. The blade is typically 30 to 66 centimetres (12 to 26 in) long and usually under 3 millimetres (1⁄8 in) thick. In the Spanish language, the word is possibly a diminutive form of the word macho, which was used to refer to sledgehammers. Alternatively, its origin may be machaera, the name given by the Greeks and Romans to the falcata. It is the origin of the English language equivalent term matchet, though this is rarely used. In much of the English-speaking Caribbean, such as Jamaica, Barbados, Guyana, Grenada, and Trinidad and Tobago, the term cutlass is used for these agricultural tools.

Campobasso (UK: /ˌkæmpoʊˈbæsoʊ/, Italian: [ˌkampoˈbasso] ; Campobassan: Cambuàsce [ˌkambuˈwaʃʃə]) is a city and comune in southern Italy, the capital of the region of Molise and of the province of Campobasso. It is located in the high basin of the Biferno river, surrounded by Sannio and Matese mountains.

Campobasso is renowned for the craftsmanship of blades (including scissors and knives), a fact well documented since the 14th century. It is also famous for the production of pears and scamorza (cheese). The city is home of the University of Molise and of the Archdiocese of Campobasso-Boiano.

A saw is a tool consisting of a tough blade, wire, or chain with a hard toothed edge used to cut through material. Various terms are used to describe toothed and abrasive saws.

Saws began as serrated materials, and when mankind learned how to use iron, it became the preferred material for saw blades of all kinds. There are numerous types of hand saws and mechanical saws, and different types of blades and cuts.

A hatchet (from the Old French hachete, a diminutive form of hache, 'axe' of Germanic origin) is a single-handed striking tool with a sharp blade on one side used to cut and split wood, and a hammerhead on the other side. Hatchets may also be used for hewing when making flattened surfaces on logs; when the hatchet head is optimized for this purpose it is called a hewing hatchet.

The earliest known use of the noun hatchet is in the Middle English period (1150—1500) Although 'hand axe' and 'hatchet' are often used interchangeably in contemporary usage, 19th and 20th century American manufacturers and retailers (Collins, Kelly, Vaughan, Warren, Mann; Simmons, Shapleigh, Sears, et al.) unanimously distinguished hatchets from hand axes in their product catalogs, listing them in separate groupings.
