A knife is composed of a blade with a cutting edge which is fixed to a handle, enabling you to cut various materials. Many have a fixed-blade or folding blade ideal for transportation. There is a range of types of knives used as tools so ideal for home improvers and professionals. The handle of the knife which enables safe use of the blade, includes a tang which is the part of the blade held within the handle. Knives often come with partial tangs or full tangs which extends the entire length of the handle. The handles are normally structured to give strength and support to the knife.
