I just realised that some of the teeth of my ceramic grater came off after I used it to grate a small apple and a carrot recently. That really surprised me as I had not bothered to take a close look at the grater in the past. I supposed I ended up eating the broken ceramic parts!
It was a cheap made-in-china ceramic grater which cost much less than the Kyocera. Now I wonder whether I should replace it with the Kycera ceramic grater? Someone wrote in Amazon's review that she noticed some of the teeth came off while other users commented theirs are ok. I hope those who have used the Kyocera ceramic grater for some time will give some comments. Thanks!
