The dual grater combines two popular grating surfaces in one unit: Fine for citrus zest, parmesan, cinnamon and nutmeg; Coarse for soft cheeses and vegetables. Features exclusive Surface Glide Technology: a grooved grating surface that allows you to grate more with less effort. Grooves reduce resistance, making it easier to grate food. Grooves also elongate the length of each individual blade; more food is grated with each stroke. Non-slip ends provide stability and safety while grating; safety cover protects hands during use.
