Zester

A zester is a small tool that can be used to shave fine threads from the peel (zest) of lemons and other citrus fruits. 

It consists of a handle and a metal head with (usually four to six) 'eyes', with which one scrapes along the peel. 

To make this easy, the edges of the 'eyes' are razor-sharp. The shavings are often used as a flavouring or (possibly dried) as a decorative garnish.
