History of Tools Through Human’s Development

How did the first tool come about? Some anthropologists believe that the beginning of this mysterious story dates back to prehistoric times, when the ancestors of man had already learned to use stones for purpose. This is believed to be the origin of tool history.

Tools are probably as old as mankind itself. Humans have always made and utilized a variety of assistive devices and used them for their own purposes, which is considered to be the biggest difference between us and other species.
Today, with this article, we will introduce you to the history of tools, and how they have changed.

The Beginnings of the Tools
The word tool first appeared in the 12th century. Even though it was created just a few hundred years ago, tools have been with mankind from prehistoric times until today.
Back then tools were certainly much simpler than they are today, but they still provided considerable benefits to humans. The earliest tools were made of stone and wood. These early stone tools were developed at least 2.6 million years ago and were used primarily for hunting and survival. Even back then, our ancestors exploited raw materials to a considerable extent. For example, tree branches were sharpened and used as spears.
The process of tool making was initially evolved in the Bronze Age - out of the need to develop agriculture at the time when mankind began to develop.In the Iron Age, man began to make more durable tools, mainly in connection with the discovery of iron. From that time on, this material could be used effectively for making tools and weapons.
This was followed by a rapid development of the tool-making industry, which continued in a more precise and rapid manner.

Evolution of Hand Tools
In principle, historians consider "hand tools" to be and only those tools that require human intervention.
The date of creation of the first hand tools cannot be determined, but we believe it was sometime during the Neolithic. When primitive people wanted to break something in some way, a heavy stone with a wooden stick, a hammer was born.
The hammer is among the most basic hand tools, utilizing a vertical force. Tools based on vertical force are called tools of the first family, which is called the first hand tools. Through evolution, we got different types of hammers from it.
Then comes the second family of tools, which are cutting tools. Initially awls and needles evolved into knives, which in turn evolved into cutting weapons (swords, daggers, etc.). In the more specific field of tools, the knife is the origin of the scissors (a combination of two knives). The application of teeth to the blade of a knife to increase its penetrating power when cutting created the first saw.
The third family is the lever tool. The lever is one of the simplest tools and its origin can be traced back to prehistoric times. A common representative of this class of tools is the shovel, which uses the principle of leverage to amplify the force exerted by the user, thus accomplishing some tasks that cannot be done with bare hands.
The shovel was a great advance in performing agricultural tasks and from it came the harrow, the hoe and even the plow. Pliers and wrenches also utilized the same principle.
The later discovery of the rotational movement of the body around an axis gave rise to a fourth family of tools: the roller, the wheel, and later the gear and pulley. Today, rotation is an essential element in the operation of numerous power and hand tools (drills, circular saws, etc.).

Tools Today
Today, there are countless types of tools available, and they don't stop evolving. Some classic hand tools continue to improve in detail and versatility, and there are always impressive new technologies in the field of power tools. The history of tools is still far from the end.

Wall Painting Tools And Equipment Preparing Guide

Renovation is a big project, but the idea of changing the color of your home's walls is something that often comes up. But going to the nearest hardware store on a whim and picking up a roller or brush and a big bucket of paint is not a good idea.
If you're getting ready to do some painting and decorating work in the near future, whether you're a homeowner or a professional, the first step is to make sure you're prepared. Few things are worse than being halfway through a painting job and suddenly realizing you're missing an important tool.
So to help you avoid that, we've put together a list of all the necessary painting tools and equipment you'll need when painting your walls. Read on to get the tips!

1. Painter's Tape
The reason why the number one item needed to paint a room is painters tape is because no one wants to get the other surfaces in the room dirty while they are doing the painting.
Plastic or canvas paint covers can also protect furniture from spills, but paint tape has the added advantage of helping you better select the areas you want to paint. And these little tools are also very inexpensive. You don't even need to buy a special roll of "professional painters tape", any ordinary tape will do the job.

2.Paint, Brushes And Rollers
Tools and equipment list:
-Interior paint primer (one that’s suitable for the paint you’re using)
-Interior paint - either oil or emulsion
-Paint kettle and paint can opener (or flat head screwdriver)
-Paint roller set: paint roller, sleeve and tray
-Paint brushes
-Radiator brush
-Paint roller extension pole
-Plastic bucket and sponge
Most of this is obviously fairly straightforward and self-explanatory - after all, you can't do much painting without a brush or roller! But for smaller rooms, a paint roller extension pole can be particularly helpful and ensures that you can do most of your painting from the floor rather than from a ladder, so you can avoid any unnecessary risk of falling from heights.
The radiator brush is angled to the brush head, which helps you move around obstacles and corners, but still gives you complete control so you don't brush on any areas you don't want.
Also, a plastic bucket and sponge can help you wipe off any paint spills on woodwork, as some colors can stain lighter glossy finishes. The sponge can also be used to wipe the cleaning products off the walls so that they are ready for painting.

3.Personal Protective Equipment
Tools and equipment list:
-Decorator’s overalls
-Painter’s goggles
-Dust masks
-Gloves
-Shoe covers
Personal protective equipment is an important element of any job, and it's no different when it comes to painting. Painting may not sound like a dangerous task, but you shouldn't take any risks for your health.
Equipment such as goggles and dust masks can protect the most sensitive parts of your face - dust masks in particular can help prevent the inhalation of harmful fumes or particles.
Some people may also be allergic to substances contained in paint. So wearing gloves while painting to prevent direct contact between paint and skin is also a good idea. Shoe covers may not always be as necessary, but they are still useful if you need to protect furniture and carpets.
These personal protections may not be strictly necessary for every job, but we say it's better to be safe than sorry.

Common Uses of Pliers: What Are They For?

Pliers are an important part of every toolbox, and they have multiple uses in industry and at home. As a multi-purpose hand tool, pliers are used primarily for gripping, bending and cutting. Two crossed metal limbs provide tough leverage that multiplies the strength of the user's hand.

While you can usually use a one-size-fits-all model, there are different classifications of pliers available for specific tasks. Choosing the right pliers for the right job will improve efficiency and safety.

Common Uses of Pliers

Gripping

The primary use of pliers is for gripping. You can use them to loosen or tighten bolts, grip objects for stability, or pull out pins, nails, or other fasteners.

For example, slip joint pliers are a utility pliers designed for gripping and transmitting torque. They have relatively flat jaws with teeth for gripping small objects and a rounded, toothed opening for gripping larger objects, such as bolt heads and nuts.

Many pliers also have a small scissor-like section for cutting wire. Tenon pliers work similarly to multi-purpose pliers, but have long handles and offset or angled jaws for improved leverage. The jaws are height adjustable and can open wide to grip pipes and large nuts.

Bending/Straightening

The pliers can also be used for bending or straightening. The cross brace of pliers gives them superb torque power to bend and twist objects such as sheet metal, nails and wires.

All pliers can help bend things, so the kind you choose depends largely on the specific object you need to bend. Long-nose pliers or needle-nose pliers help you grip small objects that may be difficult to reach. Electricians usually use lineman's pliers to bend wires and cables.

Cutting

Some pliers can also cut wires and nails. Diagonal cutting pliers and side-cutting pliers, often called wire cutters, are primarily used to cut and sever wires. In most cases, their jaw construction makes wire cutters less suitable for gripping large objects, such as bolts. However, they are still considered pliers because of their ability to effectively grip and remove nails.

Splicing Wires/Stripping Insulation

Electricians use a variety of special pliers to splice wires and strip insulation. For this task, lineman's pliers are a popular choice. Using the wire cutter feature, you can cut through the insulation of one wire and strip off a small section to reveal the bare wire inside. If you do the same thing to another wire, you can use the pliers to help join or splice the two wires together.

Safety Tips for Using Pliers

Following are the safety measures that you should take while using pliers:

-Check the wire cutting capability of the pliers as well as all other features before using them for a specific application. When choosing the perfect pliers for your application, it is best that you have the necessary knowledge of all types of pliers.

-Always use pliers to cut wires at right angles. 

-Some people often use a hammer to strike the pliers to cut thicker wires. This activity may damage your hands and the pliers. Therefore, never use a hammer on pliers or use pliers as a hammer.

-Do not put the pliers in a place where the temperature is very high. If the pliers are left in a place where the temperature is too high, the characteristics of the tool may change and no longer do the job perfectly. The plastic handles of some pliers may also be damaged by excessive temperatures.

-If you want to increase the life of your pliers, then you have to maintain it properly. Clean it regularly and you can oil the pliers every once in a while.

-Do not use the pliers to tighten the nuts. 

In this way, we have introduced the main uses of pliers, their types and some safety precautions. We hope this article has been helpful to you. If you have any questions, feel free to visit our website.

The History Of The Axes

The Oldest Axes

The axe is one of the oldest tools used by human. The oldest axes are known as hand axes.
A handaxe is a pear-shaped, roughly cut stone tool with a wide handle. Handaxes may have been used for many different tasks, from butchering animals to digging up tubers. Gradually, the design was refined to include knives, scrapers, and arrowheads.
When much later the axe was given a wooden handle, several different types of axe heads were developed. They can be divided into two main categories: non-axe bore type axe heads and axe bore type axe heads.

Bronze Age Axe Heads
During the Bronze Age (2000 BC to 500 AD in Northern Europe), stone axes began to give way to axes with copper and bronze heads. Initially, these axe heads were often pure replicas of stone axes. Bronze axe heads were cast in molds, allowing their design to be reproduced and mass-produced.
One type of Bronze Age axe head is the socketed axe head, where the axe handle is secured in a socket at the end of the axe head. Since this axe head was hollow and the handle was inserted into the axe head, a perfectly functional working axe head could be made with a minimum of material. Earlier socketed axe heads were quite long, but they were gradually replaced by smaller types in which the out-turned edge compensated for the smaller size.
At the beginning of the Iron Age (c. 500 B.C. in northern Europe), older axe types, such as socketed axes, were simply copied onto iron, but the possibility of new materials led to a gradual change in the appearance of axe heads. Axe heads without shaft holes disappeared and were replaced by axe heads with holes for handles. Axe heads also became larger, with wider blades.

Axes As Weapons
Like the club and the spear, the axe is one of man's oldest weapons for close combat. The earliest axes used as weapons were probably those used as tools, as these were close at hand.
"Ordinary" axes were used as weapons until recent times, and then gradually special axes for combat were born. Axes produced for the specific purpose of being used as a weapon in combat are called battle axes. People began making such axes as early as the Stone Age and the Bronze Age.

Axe Manufacture Today
With the development and application of modern machinery, the axe has disappeared from the realm of the forest industry. Chain saws and harvesters have completely replaced hand tools for processing millions of cubic meters of pulpwood and timber.
The axe is now used more for small jobs in agriculture, home and outdoor sports, just as it was before the rise of the forest industry. Many people also choose to use power tools like chainsaws, but the axe still has an irreplaceable role in certain jobs as a most basic hand tool.
Even the axes manufactured today are very different from when man first utilized this tool. Modern processes allow axe handles to be made of materials other than wood, such as rubber and fiberglass. They may be stronger, lighter, and can also fit the hand better for gripping. Stronger carbon steel is also used for the axe head, which brings very powerful cutting ability.
However, there are still very few manufacturers producing handmade axes. More specialized craftsmanship takes more time, and many other tools are used in the making process. For today's handmade axes, the most important factor is quality, not quantity.

Essential Hand Tools for DIY Beginners

Taking care of a house has a variety of repair challenges, such as redecorating or moving in for the first time, then you may have to face some DIY work. With so much equipment, tools and products available to the novice, it can be overwhelming to know where to start. What do you really need to get started with DIY?
Don't worry, we've put together a list of basic tools for anyone who needs a do-it-yourself or DIY enthusiast newbie. If you're struggling with small repairs and installations, or want to solve home routines on your own, read on for guidance!

Safety Equipment
You can never go wrong investing in some safety equipment. If you're decorating or sanding, dust masks will come in handy. These masks are fine for sawdust and plaster dust, but for very fine powders, paint fumes and other chemicals, it is recommended that you purchase a respirator.
A pair of safety glasses is absolutely essential. Eyewear that meets the low impact protection standard will meet the need for eye protection in most scenarios. Loud noises - especially in an enclosed space - can be uncomfortable and can even damage your hearing. When using power tools at home, a simple pair of ear protectors will provide proper protection from loud noise.
Work gloves are an inexpensive way to protect your hands from minor abrasions and reduce discomfort during long hours of work. Likewise, foam mats or knee pads can be helpful in protecting your knees during long hours of work.

Measuring Up
For DIY, there are few measuring tools more important than a tape measure. No matter how keen your eyes or steady your hands, you can't just pick and choose. Even if you're just measuring furniture, your trusty tape measure is your best friend, along with a level to keep things straight.

Hand Tools
Screwdrivers are the DIY tool you'll use most often, so investing in a decent set will probably get you hundreds of jobs done. With so many different accessories, sizes and lengths of screwdrivers, it's easy to get carried away, but for everyday use, a Phillips head and flat head set is a solid starting point.
Similarly, a solid set of hex keys (also called allen wrenches) is another toolbox necessity due to the mass appeal of flat-pack furniture.
For all the finesse of modern fittings and fixtures, you'll still need a hammer, and a classic "claw" hammer is a good choice to start with. For putting nails in the house, removing them from fixtures and walls, and applying leverage where needed, a solid hammer is a lifelong tool.
An adjustable wrench is the most basic tool for handling nuts, bolts and pipe work with a simple twist. For pulling and prying off small fittings, you'll need at least one set of pliers.

Other Essentials
In addition to the various safety protection devices and basic tools mentioned above, there are many other accessories that are well worth the investment. They may not look impressive, but they can make your job a lot easier.
First, we recommend that you purchase a toolbox or bag. You don't want to have all your tools cluttered together and not be able to find the one you need when you use it. Use a toolbox to organize and protect your tools.
For quick fixes, a sturdy roll of duct tape is another must-have you'll need at some point. Whether you're sealing, wrapping, or making a temporary fix, duct tape is a back-up tool that takes a larger place in your toolbox.

Of course, if you're still not sure where to start, SINOTOOLS has a combination tool kit for you as well. It contains most of the basic tools mentioned above to help you get started on your DIY journey.
