Orthodox prayer for the blessing of any object

O Creator and Author of mankind, Giver of spiritual graces and Bestower of eternal salvation: Do Thou, the same Lord, send down Thy Holy Spirit, with a blessing from on high, upon this (name of object), that, fortified by the might of heavenly protection, it may be potent unto bodily salvation and succor aid aid, unto all who shall desire to make use of it, through Jesus Christ our Lord. Amen.

May Christ our true God, through the intercessions of His all-immaculate Mother and of all the saints, have mercy upon us and save us, forasmuch as He is good and loveth mankind.

Through the prayers of our holy fathers, Lord Jesus Christ our God, have mercy upon us and save us. Amen.
