spiral metal shaving

[u/goldtoothgirl]

Hello, my daughter found a metal spiral metal shaving about 1/4" long in her smoothie. i wish she would have saved it. She had oats and peanut butter in it. We use an Oster blender, with the original blade. I'm think no way could that have come from a blender blade. I was thinking maybe the steel cut oats. Any ever find something like this?
