This is my first batch of garlic graters! I have never used one before, but I did test these and I think it works! Please feel free to give me any feedback so I can improve for the next batch. I'm thinking I'll ultimately price these around the $25-30 range, but since these are my prototypes, I'm pricing them at $18.
I plan to use mine to grate garlic and then pour olive oil into it and dip bread in it. You can also scrape the garlic (or ginger) out of it with a pastry or basting brush.
