The index finger or forefinger is the second finger of a humanhand, located between the thumb and the middle finger. It is usually the most dexterous finger of a hand and is usually used to point to things (a direction, an object etc.), thus it is also called the pointer finger.
Gestures
As mentioned above, the forefinger can be used for pointing. However, this gesture is considered rude in some countries (Brunei, for instance), and other gestures are used instead.
A lone index finger often is used to represent the number1, or when held up, it can be an admonitory gesture.
A hunting glove includes a forefinger sheath which is formed by combining a back-side cover pre-oriented towards the thumb, a fourchette inwards pre-curved towards the palm and a thenar-side cover shorter than the forefinger length so as to form a forefinger sheath pre-oriented in a style suitable for triggering a gun smoothly and precisely.
