RiversideLen, I had seen that grinder when I was on Amazon looking. I didn't pay any attention to it, because it didn't look like what Mike had described. I'll probably end up buying it. Thanks!
Thanks to you, too, Mike for the picture.
Like BakerAunt, I now use my Micrcoplane rasp grater for nutmeg. The way I measure the nutmeg is by where I buy it. McCormick's . . . their rep told me that 1 whole nut is about 1 teaspoon grated. So if I want half a teaspoon, I grate approximately half of one piece of nutmeg. I've never been disappointed in this "measuring tool."
