A modern hammer is directly descended from ancient hand tools
A modern hammer is directly descended from ancient hand tools

A tool is a device or a piece of equipment that typically provides a mechanical advantage in accomplishing a task or enables the accomplishment of a task not otherwise possible. The most basic tools are simple machines. For example, a crowbar simply functions as a lever. The further out from the pivot point, the more force is transmitted along the lever. When particularly intended for domestic use, a tool is often called a utensil. Tool is a Grammy-award winning American rock band, formed in 1990 in Los Angeles, California. ...

Observation has confirmed that multiple species can use tools, including monkeys, apes, several birds, sea otters, and others. Philosophers originally thought that only humans had the ability to make tools, until zoologists observed birds[1] and monkeys[2][3][4] making tools.

Functions

There are 5 broad categories of tools. Tools directly help people accomplish tasks. They often employ the principles of a simple machine, which is a device that only requires the application of a single force to work. Many tools or groups of tools serve to perform one or more of a set of basic operations, such as: This article is about the concept in physics. ... For other uses, see Force (disambiguation). ...

  • Cutting tools, such as the knife, scythe or sickle, are wedge-shaped implements that produce a shearing force along a narrow face. Ideally, the edge of the tool needs to be harder than the material being cut or else the blade will become dulled with repeated use. But even resilient tools will require periodic sharpening, which is the process of removing deformation wear from the edge. Also gouges and drill bits.
  • Moving tools, move huge and tiny things, e.g. concentrating force tools like the hammer moves a nail, the maul moves a stake, or a whip moves flesh on a horse. These operate by applying physical compression to a surface. In the case of the screwdriver, the force is sideways and called torque. Writing implements deliver a fluid to a surface via compression to activate the ink cartridge. Also grabbing and twisting nuts and blots with pliers, a glove, a wrench, etc...) All these tools move items by some kind of force. Also Trucks, Rockets and Planes move larger items.
  • Guiding and measuring tools include the set square, straightedge and theodolite.
  • Shaping tools, such as moulds, jigs, trowels, concrete forms, caulk, concrete.
  • Fastening tools, such as welders, rivet guns, glue guns, glue.

Tool substitution

Often, by design or coincidence, a tool may share key functional attributes with one or more other tools. In this case, some tools can substitute for other tools, either as a make-shift solution or as a matter of practical efficiency. "One tool does it all" is a motto of some importance for workers who cannot practically carry every specialized tool to the location of every work task. Tool substitution may be divided broadly into two classes: substitution "by-design", or "multi-purpose" use, and substitution as make-shift. In many cases, the designed secondary functions of tools are not widely known. As an example of the former, many wood-cutting hand saws integrate a carpenter's square by incorporating a specially shaped handle which allows 90° and 45° angles to be marked by aligning the appropriate part of the handle with an edge and scribing along the back edge of the saw. The latter is illustrated by the saying "All tools can be used as hammers." Nearly all tools can be re purposed to function as a hammer, even though very few tools are intentionally designed for it. In woodworking and carpentry, Hand saws are used to cut pieces of wood into different shapes. ... In carpentry, a square or set square is a guide for establishing right angles (ninety-degree angles), usually made of metal and in the shape of a right triangle. ...


Multi-use tools

  • A Multitool is a hand tool that incorporates several tools into a single, portable device.
  • Lineman's pliers incorporate a gripper and cutter, and are often used secondarily as a hammer.
  • Hand saws often incorporate the functionality of the carpenter's square in the right-angle between the blade's dull edge and the saw's handle.

A multitool is a portable, versatile hand tool that combines several individual tool functions in a single grip or in the shape of a credit card. ... Linemans pliers are a specialized type of side-cutting pliers used by Electricians and other tradespersons to cut and bend wire and cable, and to hammer other small tools, such as a chisel or screwdriver, and to hammer various types of hardware, especially staples and small nails. ... For other uses, see Hammer (disambiguation). ... A crosscut handsaw In woodworking and carpentry, hand saws, also known as panel saws, are used to cut pieces of wood into different shapes. ... In carpentry, a square or set square is a guide for establishing right angles (ninety-degree angles), usually made of metal and in the shape of a right triangle. ...

History

Main article: History of technology

Evidence of stone tool manufacture and use dates from the start of the Stone Age, though it is possible that earlier tools of less durable material have not survived. Stone tools found in China magnetostratigraphically date back to approximately 1.36 million years ago. The transition from stone to metal tools roughly coincided with the development of agriculture around the 4th millennium BC. The wheel was invented circa 4000 BC, and has become one of the worlds most famous, and most useful technologies. ... Ancient stone tools A stone tool is, in the most general sense, any tool made of stone. ... Stone Age fishing hook. ...

For other uses, see Mechanic (disambiguation). ...
