I usually cutting onions with choppers but if I have a large amount I need diced, I peel and quarter them and throw in a blender (Osterizer) and top with water. A few pulses and then I pour them into a mesh wire strainer. Repeat as needed. The onions are chopped nicely and it tames them down some to boot! Wearing disposable gloves keeps the hands smelling clean and is the smart thing to do anyway.
Yes, I have something similar. I use a Mueller slicer to cut onions. I just need to cut the onion in half and place it on the blade. Press it down and lay the neat onion in the box under the blade. I’m so glad I never shed tears again, and it saves me a lot of time preparing salads.
I’ve seen this kind of spam before, where they will quote somebody and subtly change the quote to hide a link in the quote that wasn’t originally there.
