I know that the Pope was called by name 3 times, but I don't know about the silver hammer this time. Silver Ring and Rituals:

The pope's camerlengo (chamberlain) has to officially confirm his death and then seals his private apartment, prepares the funeral and the conclave to elect a successor.

The camerlengo and three assistants chosen by lot from among the cardinal electors to decide when the pope's body is to be taken into St Peter's Basilica for public viewing. They also make sure the Pope's Fisherman's Ring and his lead seal are broken so they cannot be used by anyone else. No autopsy is performed.

Funeral rites last nine days, with the date of the funeral and burial to be decided by the cardinals between the fourth and sixth day after his death. Popes are laid to rest in the crypt underneath St Peter's Basilica.

They are traditionally buried in a casket of cypress wood which is sealed inside a larger lead casket and then covered with an outer pine box.

This is what I found in Internet:

"When a Pope dies, the "Cardinal Camerlengo" (Cardinal Chamberlain, known as the "Camerarius" in Latin) first verifies the death. Traditionally, this is done by striking the Pope's forehead gently thrice with a silver hammer while asking him, using his Baptismal name, if he is dead, e.g., "Karol Wojtyla, are you dead?" When there is no response from the dead Pope, the Camerlengo solemnly announces his death and removes the Fisherman's ring from the dead Pope's finger. This ring, along with the papal seal, are broken, and the Pope's bedroom and study are sealed up. The bronze doors of St. Peter's Basilica are closed, while its bells toll the death, and all the bells of Rome join in."

Extract from the Apologia.

I have still not found much evidence on the silver hammer though it may have been used



. Speaking of Pope's... in Italy we have a saying As we say in Italy...

"Morto un Papa, si fa un'altro"

However I really do think it rather inappropriate when taken literally ("When a Pope dies they make another"), however what it really means is different. Its is used in a variety of circumstances... eg. A man and a work collegue miss a train. The man's collegue is worried that they may arrive late and get fired. The man turns to his co-worker and fatalistically says... "Morto un papa si fa un altro" which would mean... That if they get fired they will find another job

This saying goes back over a thousand years to Pope Leo, who crowned Charlemagne Holy Roman Emperor. When he died Charlemagne's son was said to have bluntly said... "Morto un Papa si fa un altro" in Latin though.
