I believe it can happen if the stalk is in an inverted u-position. The blade can act like a keystone in an arch as it makes the cut.So I’m new here but... is that wedging on celery thing a joke?
Where the f-word do u wedge on celery?
I know this is one of things that will be obvious to me once you’ve explained how you mean.
(Also I used to cut celery when I was bored at work, and then just would throw it out, it’s practically free and I was the one doing the ordering anyways)
