With the showpiece Four Hills looming large Schlierenzauer was in impressive form in Switzerland, racking up a points tally of 273.7 to take the victory.
That win takes him just three away from the all-time record holder, Finland's four-time Olympic gold medallist Matti Nykanen.
And as an added boost victory means the 22-year-old Schlierenzauer now sits top of the overall World Cup points table with 448 to his name.
It was a close fought affair with Andreas Kofler very nearly bagging himself a weekend double and a third win on the bounce but the Austrian was forced to settle for second behind his compatriot with 270.3 points.
Germany's Andreas Wellinger was third, also on 270.3 points a new personal best while Severin Freund could only manage sixth.
Freund's poor day's work sees Schlierenzauer overtake him at the top of the overall standings with 448 points while Kofler is up to third overall and Wellinger is fourth.
