The only time anyone gets cut is when someone else either interrupts them, distracts them, or they get distracted and over-confident.
It can take only a few seconds to forget where the edge is and slip.
We are all extremely careful here and do a very good job of avoiding Injury daily.
As a reference; I've only cut myself with our knives, three times in all the years i have worked here.
That doesn't include all the paper cuts, cardboard cuts, and slips ups with an exacto blade though....
