Slice in no time. Whether you're preparing classic Hasselback potatoes or experimenting with root vegetables like parsnips and the like, you'll quickly achieve impressive results. The hasselback cutter consists of a frame with large handles and sharp steel blades, along with a pusher that fits into the frame. The potato is placed on the chopping board, the hasselback cutter is positioned over it and pressed down. This causes the blades to cut deep grooves into the potato without slicing all the way through. As the cutter is pressed down, the pusher moves upward. When you then press it down again, the potato is pushed free from the blades. It really is that simple.
