Hand Tools and workshop equipment

A tool is an object that can extend an individual's ability to modify features of the surrounding environment. Although many animals use simple tools , only human beings, whose use of stone tools dates back hundreds of millennia , have been observed using tools to make other tools. The set of tools required to perform different tasks that are part of the same activity is called gear or equipment. While one may apply the term tool loosely to many things that are means to an end e.

If repeated use wears part of the tool down like a knife blade , it may be possible to restore it; if it wears the tool out or breaks it, the tool must be replaced. Thus tool falls under the taxonomic category implement , and is on the same taxonomic rank as instrument , utensil , device , or ware.

Anthropologists believe that the use of tools was an important step in the evolution of mankind. Stone artifacts only date back to about 2. This finding pushes back the earliest known use of stone tools among hominins to about 3. Finds of actual tools date back at least 2. Now, more tools are recognized as culturally and historically relevant. Tools are the most important items that the ancient humans used to climb to the top of the food chain ; by inventing tools, they were able to accomplish tasks that human bodies could not, such as using a spear or bow and arrow to kill prey , since their teeth were not sharp enough to pierce many animals' skins.

Based on marks on the bones at archaeological sites, it is now more evident that pre-humans were scavenging off of other predators' carcasses rather than killing their own food. Mechanical devices experienced a major expansion in their use in Ancient Greece and Ancient Rome with the systematic employment of new energy sources, especially waterwheels. Their use expanded through the Dark Ages with the addition of windmills. Machine tools occasioned a surge in producing new tools in the industrial revolution.

Advocates of nanotechnology expect a similar surge as tools become microscopic in size. Some tools may be combinations of other tools. An alarm-clock is for example a combination of a measuring tool the clock and a perception tool the alarm.

This enables the alarm-clock to be a tool that falls outside of all the categories mentioned above. There is some debate on whether to consider protective gear items as tools, because they do not directly help perform work, just protect the worker like ordinary clothing. They do meet the general definition of tools and in many cases are necessary for the completion of the work. Personal protective equipment includes such items as gloves, safety glasses , ear defenders and biohazard suits.

A simple machine is a mechanical device that changes the direction or magnitude of a force. 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 makeshift solution or as a matter of practical efficiency.

Tool substitution may be divided broadly into two classes: substitution "by-design", or "multi-purpose", and substitution as makeshift. Substitution "by-design" would be tools that are designed specifically to accomplish multiple tasks using only that one tool.

Substitution as makeshift is when human ingenuity comes into play and a tool is used for its unintended purpose such as a mechanic using a long screw driver to separate a cars control arm from a ball joint instead of using a tuning fork. In many cases, the designed secondary functions of tools are not widely known.

The latter is illustrated by the saying "All tools can be used as hammers. Tools are also often used to substitute for many mechanical apparatuses, especially in older mechanical devices.

In many cases a cheap tool could be used to occupy the place of a missing mechanical part. A window roller in a car could easily be replaced with a pair of vise-grips or regular pliers. A transmission shifter or ignition switch would be able to be replaced with a screw-driver. Again, these would be considered tools that are being used for their unintended purposes, substitution as makeshift. Tools such as a rotary tool would be considered the substitution "by-design", or "multi-purpose".

This class of tools allows the use of one tool that has at least two different capabilities. Tools such as this are often power tools that come with many different attachments like a rotary tool does, so you could say that a power drill is a "multi-purpose" tool because you can do more than just one thing with a power drill.

A multi-tool is a hand tool that incorporates several tools into a single, portable device; the Swiss army knife represents one of the earliest examples. Other tools have a primary purpose but also incorporate other functionality — for example, lineman's pliers incorporate a gripper and cutter, and are often used as a hammer; and some hand saws incorporate a square in the right-angle between the blade's dull edge and the saw's handle. This would also be the category of "multi-purpose" tools, since they are also multiple tools in one multi-use and multi-purpose can be used interchangeably — compare hand axe.

These types of tools were specifically made [ by whom? To these workers these types of tools were revolutionary because they were one tool or one device that could do several different things. With this new revolution of tools the traveling craftsman would not have to carry so many tools with them to job sites, in that their space would be limited to the vehicle or to the beast of burden they were driving.

Multi-use tools solve the problem of having to deal with many different tools. Observation has confirmed that a number of species can use tools including monkeys , apes , elephants , several birds, and sea otters. Philosophers originally thought that only humans had the ability to make tools, until zoologists observed birds [12] and apes [13] [14] [15] making tools. Now the unique relationship of humans with tools is considered to be that we are the only species that uses tools to make other tools.

Recently, a Visayan warty pig was observed using a stick in digging a hole on the ground at a French zoo. A telephone is a communication tool that interfaces between two people engaged in conversation at one level. It also interfaces between each user and the communication network at another level. It is in the domain of media and communications technology that a counter-intuitive aspect of our relationships with our tools first began to gain popular recognition.

Marshall McLuhan famously said "We shape our tools. And then our tools shape us. From Wikipedia, the free encyclopedia. For other uses, see Tool disambiguation and Equipment.

Hand Tools and workshop equipment

Hand tool , any of the implements used by craftspersons in manual operations, such as chopping, chiseling, sawing, filing, or forging. Complementary tools , often needed as auxiliaries to shaping tools, include such implements as the hammer for nailing and the vise for holding. A craftsperson may also use instruments that facilitate accurate measurements: the rule, divider , square , and others. Power tools—usually handheld motor-powered implements such as an electric drill or electric saw —perform many of the old manual operations and as such may be considered hand tools. A tool is an implement or device used directly upon a piece of material to shape it into a desired form. The present array of tools has as common ancestors the sharpened stones that were the keys to early human survival.
