朽木白哉 5 This tool saves me so much time! I often bake apples, especially in fall/winter, so this saves me a lot of time and effort coring apples. It is a bit more narrow than the cores of Japanese apples though (which tend to be large), so I often have to push it through a second time in another direction. It's fine for just one apple at a time, but if I were coring many apples daily I might get tired of it.
