Day 130 hates this thing

I don't really like eating whole apples at work out of fear that I'll have food in my teeth when someone talks to me post-apple devouring. This is a real office fear. So instead I slice them. Most days I use this fancy apple slicer thingy. But 8 out of 10 times this thing gets stuck halfway through the freaking apple. I'm not sure if the blades are dull or perhaps that my arm strength is that of a toddler, but whatever it is - it is frustrating and so not what I want to deal with at 9am. Can someone invent one of these that, ya know... work? Pretty please? Thanks. :)
