Core an apple and make apple rings with just a knife. I have used apple corers in the past but they never seem to cut correctly, either leaving some of the core and seeds, or taking too much apple with it. This way you can get maximum appleage without any of the seeds.
Step 1: You will need: 1 apple and a knife
I like to use Golden Delicious apples as they have that wonderful SNAP and crispness. Use a knife with a rounded edge, not a pointed one like a steak knife.
