The gym has community rip/nail scissors (or really nail scissors that are used to cut rips/extra skin, etc.), nail clippers in the first aid box. The kids and coaches use them, and then just put them back...no disinfecting, just sharing and sharing. It is said not to share hair brushes, just think how much worse this is...the blood from the rip goes on the scissors/clippers, then the next person uses it, etc. ...
Does your gym do this?
