Question: A friend used my H571 to slice a few bananas but accidentally sliced too many. Is there any reverse mode to unslice them?  The manual is not helpful.
Document: I'm so glad they shaped the 571 like a banana. I can't tell you how many times I've accidentally used the wrong appliance, like the toaster, to slice my bananas. Before this, slicing bananas used to be so dull and boring, but now everyone in my family fights to use this thing.
This product ruined my marriage. I used to love having my wife slice my bananas for me in the morning, one slice at a time. She was great at it. I was perfectly happy with the size of the slices and her skill level. A friend sent me an email about the Hutzler 571 and I should have deleted it immediately, but I looked... a little too long. Before I knew I had ordered one. I kept it a secret from everyone.
My endless quest to slice uniform banana cylinders for my Rice Crispy cereal has come to a conclusion. A cereal friend told me about the Hutzler Banana tool. Unfortunately I thought he said hustler banana and my search was fruitless. Just like an infomercial, my kitchen has been freed of unappealing banana slicing equipment. My deli slicer,hot wire and Ginsu knives have been bunched and discarded. I've also strained tortellini, sorted blueberries and sliced boiled eggs with this godsend.
Hutzler has done it again. If you liked the Hutzler Cockroach Hammer and the Hutzler Infrared Motion-Activated Toilet Paper Dispenser, you'll wonder how you ever sliced bananas before the Hutzler Banana Slicer.Knives? Neanderthals used knives. This is the twenty-first century and important people on the go just don't have time to cut a banana One. Slice. At. A. Time. With the Hutzler banana slicer you get fast uniform slices that Neanderthals with their primitive "knives" could only dream about.
A friend of mine called me when she saw this item and I went straight to the Amazon website. I was absolutely breathless with excitement when I saw it. You see, I am, like so many millions in America, allergic to bananas. Even touching them causes my skin to break out in a pussy rash. So I knew this would enable me to do the task of slicing the banana without coming in contact with the fruit.
Like most reviewers, I was excited to purchase this product. However I was dissapointed. The instructions were confusing; I spent too long on hold with tech support; The representative I spoke with was not helpful; The device does not have a "lengthwise" mode; and there was no power-cord to preserve battery-life. All in all, I would recommend the Wagner HX-15 "Monkey's Helper" instead.
I have just one thing to say why could I not have seen this product sooner ! I have a bad habit of misusing edged utensils and as a result of using a knife to slice bananas have accidentally sliced off all but 1 of my fingers on each hand! (btw it took awhile to type this with that few digits!)
Slicing bananas and as a boomerang. I found they work well in combination too. After an exhausting stint at cutting a banana, I fling it into the living room, it loops through the dining room and returns to the kitchen with nary a banana speck left on it.Please note, while the manual does not specifically mention it, DO NOT use it as a replacement for a Kevlar vest. Also, Do not submerge your banana in liquid nitrogen then attempt a slicing session with the H571.
When I tried plugging in the Hutzler Banana Slicer, it just melted and got really hot. Recommend using it in manual mode.
Like so many people here, I've always been at a loss for dividing my bananas. I have reversed over them with my car, rolled them out with a rolling pin and nothing has ever seemed to work. It started to affect my work. I used to be so confident, but when you're the only one in the office with mashed banana stuck to your eyebrows and sleeves you start to feel pretty low. Luckily a friend let me into a secret.
Answer: Yes, I was confused as well but after some experimentation, I found that instead of pressing down the slicer onto the banana to slice, you can unslice but pushing the unused slices back through the corresponding slots.    I will post video on youtube when I have a free moment.   I... just... can't stop using this amazing product.
