What are the different parts of a zester called? Earlier I was trying to describe which part of a zester to use and realized I have no idea what the different parts are called. I fell back on google, and was surprised to find nothing, there are plenty of zesters for sale, and plenty of people incorrectly calling microplane graters zesters but no terminology. 

What are these parts of a zester called?
#1 is the zester.
#2 is called a channel knife, and is used to create a wider strip of zest for garnish.
