I haven’t tried it on an apple yet, but recently found a Case 4100 in my girlfriend’s dad’s collection. It’s effectively new. We use it as a letter opener. Hand for scale.There is also another traditional pattern which excels at slicing and peeling apples: the fruit or sausage testers. they have long, flat ground spear point blades, the best sizes fir this tasks are the ones with 4 to 5 inches, for me the 4-4.5 inch being the sweet spot.
In Hungary there is a version called the “szalonnázó”, i. e. the bacon slicer. There is another variant with a somewhat wider blade, called the “rác bicska”, i. e. the Serbian pocketknife. I personally like this one the best.
