For DIY enthusiasts, and even those who have the bare basics of a tool box, most people will probably have at least some hand and power tools to call their own. The simple difference between a hand and power tool is that hand tools are devices for performing work on a material using only hands while the power tools are tools powered by an electric motor.
Arguably hand tools and power tools are great machines for completing large scale projects quickly and efficiently, and other tasks which require more than man power to get the job done. Meanwhile, hand tools can mean the difference between a casual DIY beginner and a true craftsperson for smaller projects. A degree of skill and precision can come into the use of hand tools, while the main element of using power tools is the safety aspect.
Hand tools usually refer to anything which is manual, and there are many which are so common and every day, that we do not even think of them as tools at all. These range from gardening equipment such as spades and shovels, to hammers and screwdrivers. These items are so prevalent in our daily lives we would not necessarily consider them when considering the tools we own.
