Staff, Stave
Several different kinds of staves are borne in coats of armour, as follow:
Papal staff
Papal Staff or pope’s cross staff, sometimes called a treble cross staff and also the universal bishop’s treble cross, but more properly blazoned a staff pommelled and fitched, the top being treble crossed paté bottoné, and by some, a treble cross, the second and third crossed paté bottoné.

A bishop's cross staff
The cardinal and patriarchal cross staves have a double cross paté, the first single, the other crossed; and the bishop has but a single cross on his staff, as borne in the Arms of the Archiepiscopal See of Canterbury.
