Hand tools have always been the best friends of mankind since its days as cave dwellers who hunted animals for food. Tools made of sticks and stone were used to build settlements break rocks or a particularly hard nut. In this day and age hand tools have evolved in all ways conceivable by mankind and they are still evolving. However, the basic function of every tool remains the same, to make human life easier and more convenient. Despite the transition from stone to metal, this basic function remains the one constant.
