Ummm. I was sent a new combination lemon tool to test and review a few months ago and it is new on the market. Publicized as the "Ultimate Citrus Gadget"
It is very handy, can be hung up to store and is quite efficient and at a very reasonable price.
I have electric juicers and many zesters so I gave it away after I finished my review.
I should add that one can zest the lemon, cut off one end and juice the whole lemon with this reamer, instead of doing the two halves. I found it much faster and it really produces a lot of juice - I do microwave the lemons for 15 seconds (up to 3 lemons) longer for more.
