The Scout sign identifies you as a Scout anywhere in the world. Use it whenever you give the Scout Oath or Scout Law.
The hand is still held palm facing out, and the thumb holding the little finger, but the hand is held at the shoulder
The three upraised fingers stand for the three parts of the Scout Oath. The thumb and little finger together stand for the bond between all Scouts.
Meaning of the three fingers
In his book, Scouting for Boys, Robert Baden-Powell chose the three-finger salute for Scouts to represent the three aspects of the Scout Promise:
1. Honour God and the King
2. Help Others
3. Obey the Scout Law
