I think Jeekinz was attempting to use a humorous reference (Tim Allen and his popular TV sitcom show, Home Improvement - his show on the show "Tool TIme" and how his character uses, or rather misuses, tools) to make the statement that some people are getting way too testy and taking this thread way too personal if someone doesn't agree with what someone else uses, where they bought it, what they paid for it, etc.
zest: The outermost part of the rind of an orange, lemon, lime or other citrus fruit, used as flavoring
zester: a tool used to remove the outermost part of the rind of an orange, lemon, lime or other citrus fruit, used as flavoring
You can use a vegetable peeler for wide strips of zest (we used to do that when I was tending bar so when we added a twist to get the essential oil out of of the zest we were not getting the bitter oils from the pith - and we needed something wide enough to "twist"), you can use a "zester" that strips off thin (like a chiffonade) strips of zest (you can do the same thing with a vegetable peeler and a chef's knife), you can use the fine grating side of a box grater for grated zest ... the "microplane" is just the latest tool to create "grated" zest - easier and more efficient to use than the box grater.
When the TV chefs first started using, and promoting, the microplane for zesting and grating hard cheeses - they were buying them in hardware stores - they were just replacement blades for a wood shaping tool - they didn't come with handles.
There is more than one way to zest an orange/lemon/lime ...
