Physicists determined the paper most likely to give you a paper cut

An experiment with a robot and gelatine determined that 65-micrometre-thick paper is the most prone to slicing our skin – but it can also make for a handy recyclable knife.

The most dangerous type of paper is 65 millionths of a metre thick – at least when it comes to paper cuts.

“I got many paper cuts and frankly they were starting to annoy me,” says Kaare Jensen at the Technical University of Denmark. After failing to find the cause in existing scientific studies, which he says mostly focus on the risk of infection, he and his colleagues decided to set up their own experiment.
