What degree is the bevel? Do you use a "slicing" motion, or just straight down through the onion?
I wish I had a way to capture video. I use a slicing motion to cut my onions. It's like they just fall apart into diced pieces.
Vera, you'd really find the humor in this:
When I was a teenager, working at my first job in a burger join / ice cream shop, I was given a task of slicing a 50 lbs. bag of onions, prep for the weekend. We had a hand-powered, rotary slicer. The onions were at room temp. I got them peeled, then proceeded to slice them. I sliced them nonstop. In the end, I was tearing up so badly that I literally could not see; I had a film of tears completely covering my eyes.
I needed to wipe the tears out of my eyes. Before I could do that, I needed to wash the onion juices off my hands. I had to feel my way from the back room to the front line, where the hand-washing sink is. Once I had accomplished that task, cleared my eyes, and could actually SEE, what did I see, but a lady patiently waiting for ME to ring her up for a gallon of milk and a dozen eggs. She just looks at me, and asks, "What happened? Your girlfriend break up with you or something?"
I had to tell her, with a straight face, that I had just sliced 50 lbs of onions. She laughed.
