Skipped by Silvana Tirinzoni, the Swiss team proved too strong for the RCF at the WinSport Arena as they secured their eighth world title.

Six of those victories have come in the past nine editions of the tournament, emphasising Switzerland's dominance since 2012.

"It can't get any better really," said Tirinzoni.

"Just to have an amazing week and to finish it like this, it doesn't get any better."

Switzerland opened the scoring in the first end when Alina Paetz was forced to play a hit-and-stay for the single point.

After RCF blanked the second end, Alina Kovaleva had a draw for two points in the third - only to come up short of the ring and score a single point to level the game.

In the fourth end, Paetz played a double take-out with her final stone to score two points and take a 3-1 lead, before RCF opted to blank the next three ends.

Kovaleva cut RCF's deficit to 3-2 in the eighth before Switzerland blanked the ninth to retain the last stone advantage going into the tenth end.

In that tenth end, Kovaleva was light with a freeze attempt with her last stone leaving Switzerland in shot position.

But Paetz was not required to throw her final stone as Switzerland scored the single point for the 4-2 win.

"It was very important [having hammer in the tenth end], especially if you have Alina throwing last rocks," said Tirinzoni.

"She's not going to miss too many of those, so having hammer coming home is a good feeling.

"I was quite confident.

"You can't describe how it feels [to be back-to-back champions], especially after being here for such a long time.

"We can't wait to go home and bring that cup back home to Switzerland."

The RCF won silver after being forced to play neutrally due to Russia's doping sanctions.

United States, skipped by Tabitha Peterson, won their first-ever bronze medal at a World Women's Curling Championship following a 9-5 triumph against Olympic gold medallists Sweden.

The two teams were locked at 2-2 going into the fifth end break before Sweden started the second half with the first multiple-point score of the game when Anna Hasselborg bagged two points for a 4-2 advantage.

But the US responded in fine style in the seventh with Peterson removing the lone Swedish stone in the house to score five points and take a commanding 7-4 lead.

This proved to be the significant moment in the match as the US went on to a seal a convincing victory with Peterson notching two more points in the final end.
