Question: I would like to use this to make large chopped salads in a bowl.  What kind of bowl would work?  Or is it better on a cutting board?
Document: So I think that this is a good tool - it has held up well thus far and is quite good at chopping things up, particularly in a bowl but on a cutting board it works OK too.The grip is comfortable in my hand and it feels solid and sturdy.I think a two-bladed one might work better, though, like they use at Subway. I probably won't invest in one of those though.
I bought this to make chopped salads, which it does very well, but have found that I use it for slicing cheese, chopping vegetables for soup, and many other chopping/slicing uses. I use it with a plastic bowl and composite cutting boards in order not to dull the blade. I thought the included blade cover would be flimsy but it has held up well.
My first try was with onions. Was scared I would cut off my fingers as it is so sharp and the onions 'popped' all over the board. Was wishing I had one with the bowl to cut it in, but minus uniform knife cuts, worked well. Practice will make it better and will be great to cut cheese as well as veggies! Cleaned in top of dishwasher perfectly.
I love Subway's chopped salads and decided to purchase this item so that I could make them at home. I read many reviews stating that the double bladed choppers allow for food to become stuck quite frequently while chopping. This chopper is extremely sharp. I put my salad items in a large bowl and chopped away! It worked AWESOME........just like Subway!
I get chopped salads from lunch stands and was trying to do that at home. I bought this along with a large stainless steel mixing bowl and it worked like magic! Chops salads and toppings in seconds and is really easy to use. It comes with a plastic sleeve to store it in so the blade is covered although it's a cheap plastic sleeve and is already falling apart. It's a really sharp object so I'll just need to find another way to store it but other than that it's amazing.
Throw your veggies in a bowl and hit 'em with this baby a few times and you've got a chopped salad at home just like the fancy bistros at a fraction of the price! Good construction and nice handle make for ease of use and easy cleaning. A good tool for the cook or anybody who makes salads!
I like and use this Mezzalina almost every day. It does what it claims to do, and does it well. If I were to choose again, I would purchase the double bladed one. Ilove chopped salad, and although this chops just fine, two blades would be better than one ! Still, it's a good product.
I work in Manhattan and I love getting the chopped salads from the local deli. Since I make my lunch most days I decided to get my own chopper and see if I could replicate the salad experience from those salad places. YES! This chopper works great - especially with a vegetable like kale that is voluminous and dense. If it's not chopped up into small pieces it can take over the salad and overshadow the other ingredients.
I bought this hoping to duplicate Subway's chopped salads. Love this! Very sharp and easy to use. Throw your salad's ingredients into a bowl, chop away, and for some reason, it just tastes so much better. I can't eat a salad without it now.
I am obsessed with chopped salads but needed something to make making them easier. This knife has made making the perfect chopped salad a breeze. I just put the veggies. lettuce and dressing in a bowl, chop with this knife for a min. and viola, it's done and delicious. Wish I would have got this easier.
Answer: a metal bowl works fine...i just use  plastic one. The blade is sharp but has not damaged the plastic any. I prefer using  bowl because it keeps all the lettuce together and you dont have to handle it as much
