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.

The hand, sometimes including a portion of an arm, or ending about the wrist, is used to indicate the intervention in or approval of affairs on Earth by God, and sometimes as a subject in itself. It is an artistic metaphor that is generally not intended to indicate that a hand was physically present or seen at any subject depicted. The Hand is seen appearing from above in a fairly restricted number of narrative contexts, often in a blessing gesture in Christian examples , but sometimes performing an action. In later Christian works it tends to be replaced by a fully realized figure of God the Father , whose depiction had become acceptable in Western Christianity , although not in Eastern Orthodox or Jewish art.
