Did Heath Ledger make Joker more stabby than shoot-shoot?

I know the Joker wouldn't care if he killed you with a gun or knife, but I seem to recall the Joker being more trigger-happy than stabby-stab. He'd always use either regular gun or some sort of gimmick gun (boxing glove gun or whatever). I'm not sure about the comics but it seems coincidental both his appearances in the DC fighting games and the Young Justice cartoon made him wave knives around a lot more, and they both came out after The Dark Knight. Especially with that one line where Joker stated he preferred to stab his victims than shoot them to savour their last moments, I'm wondering if outside media decided to use that movie as a template to make Joker Stabber McStabby over Try to Shoot Batman with a Joker-Face Gun.
