Ceramic blades are made from the same mineral as sapphire. As long as
you only use them to cut food it is not true that they must eventually
get dull. This is a bit like saying that the anodized coating on pans
will never wear out - It's true as long as you never abuse them. So how
do you make a ceramic blade dull? By abusing them. Otherwise they do
not get dull.
