Question: Does this mezzaluna rock back and forth or does it use a 2-handed up and down chopping motion?
Document: I always wanted this chopper but wasn't sure which one to get or even what the name was. Luckily, I did a search on amazon and found the Mezzaluna. After reading the reviews on this particular one and noted it was 10 inches, I decided to purchase. I am glad I did. It has cut down my chopping time in the kitchen substantially. I am glad I got it.
This is so handy and efficient for chopping herbs, garlic cloves, nuts, whatever. Very quick to do a job that would take a lot longer with a regular knife. I never really knew what they were for and now it's in constant use. Really a neat gizmo. Should have had this years ago but I didn't know what they were for.
I bought this mezzaluna as a gift for my daughter. It's as close in size and style as I could find to the mezzaluna I purchased for myself in Tuscany, Italy. This kitchen tool makes cutting herbs so much easier. Love it! !
I wasn't sure whether I would like this or not.....but it is incredible. You can make chopped salads just like the ones at Chop't!! Good thing it has the 2 handles or you could chop your finger off. It is much more durable and sharp than I thought it would be.
A real 5-star chopping blade. Wife in rehab for a broken wrist and purchased a smaller version of this blade. Worked so well for her, she wanted a larger blade. She is now able to prepare the foods we were missing while she is mending the wrist.
Those two handles sure feel comfortable in the hands too. But the durn boomerang just don't come back. First varmint I seen, I a-grabbed the boomerang and took aim. Well, that boomerang took flight like a empty can of Coors out of a pickup window... straight down into the dirt, nearly got my best layin hen. I tried a couple more times and managed to hit the backhouse door.
She done figgered it for a mighty fine terbaccy chopper, maybe even for them vegetables city folk like to eat. I'll be dipped!
I seen this here boomerang on the Amazon store on the intertubes. Figgerin it fer a answer to the varmints done took up on my land, I ordered me one straight up. Shurnuff, a couple of days later, there it was waitin in my box at Shirl's Stihl, Package Store and Post Office.
Answer: Rocks back and forth. Use it all the time.  Love it
