As Thermomixer says, size is important, not only for ice but everything. I personally wouldn't wait until next Saturday, I would be ringing your consultant today (you don't want to do any more damage if you do happen to be doing something wrong!!
You will also need to think about what you were using your TMX for before you noticed the chips etc out of your blades as she will need this info to help you. By before I mean the last couple of days before, in case it is a combined thing if you know what I mean.
Hope you can get some answers quickly
