Handle

A handle is a part of, or attachment to, an object that allows it to be grasped and manipulated by hand.

The design of each type of handle involves substantial ergonomic issues, even where these are dealt with intuitively or by following tradition.

The inside controls for opening car doors from inside are usually pull handles, although their function of permitting the door to be pushed open is accomplished by an internal unlatching linkage.

[4] Two kinds of pull handles may involve motion in addition to the hand-focused motions described: Another category of hand-operated device requires grasping (but not pulling) and rotating the hand and either the lower arm or the whole arm, about their axis.

The handles of bicycle grips, club-style weapons, shovels and spades, axes, hammers, mallets and hatchets, baseball bats, rackets, golf clubs and croquet mallets involve a greater range of ergonomic issues.
