Who is responsible for the Arrow of Light award?

[Jeffrey H]

From the list of the Cubmaster's position responsibilities:

"Help plan and conduct impressive Webelos graduation ceremonies involving parents and guardians, the Scoutmaster, the Webelos den chief, the Webelos den leader, and the troop junior leaders."

While it is not stated who will buy and handle special AoL awards, arrows, etc. The Cubmaster does have responsibility to ensure the boys will have a meaningful ceremony. Often, providing a meaningful ceremony includes the presentation of the AoL Badges and Arrows and how they will be presented.
