Everything Svendsen has touched so far in the Czech Republic has turned to gold with the Norwegian winning the mixed team relay and the sprint both ahead of Frenchman Fourcade.
However he was made to work his hardest yet to claim a third successive gold in a dramatic pursuit race that saw four bidding for gold at the death for the first time ever in the event at the worlds.
Svendsen and Fourcade were joined by Russian's Anton Shipulin and Dmitry Malyshko, the latter the only one to shoot 20 out of 20 in the range in the 12.5km pursuit.
Fourcade made his move with 500m to go and, while the Russian's couldn't catch him, Svendsen followed with both neck and neck at the line and lunging to claim the win.
The Frenchman reached his leg for the line first before collapsing with Svendsen staying up right and celebrating after the crossing the line with a photo finish called.
As it turned out Fourcade's early lung cost him as his foot crossed the line first, but not his transponder. Instead Svendsen's did to make it three out of three for him in Nove Mesto.
Svendsen was credited with a winning time of 32:35.5minutes, missing just one target, that on his last trip to the range, with defending champion Fourcade second after failing with two.
Shipulin beat Russian teammate Malyshko onto the podium in third 3.6seconds behind Svendsen before 15 seconds separated fourth from Dominik Landertinger in fifth.
