Ceramics knives are made of the technical material zirconia,they are harder than any other cutting tools,except diamond and yet are lighter than steel.Unlike steel knives,the Ceramic blade has a smoother surface,enabling it to slice through any type of food effortlessly. This smooth surface also makes ceramic knives more hygenic.The ceramic blades will not transfer metal ions to food, nor corrode from acids or oils in fruits and vegetables.They are also corrosion free and neutral to taste making them an ideal solution in food preparation.Whats more, they will never ever rust and stay sharp for considerably longer than other knives.At half the weight of an equivalent steel knife, a ceramic knife becomes a comfortable extension of the hand,reducing fatigue during long, repetitive cutting tasks.
