To add an anecdote the other way: I fell from a late 90s playground jungle gym and manager to land my tongue on a sharp point left over from welding the thing together. Damn near tore it in half and had to get stitches. They pretty quickly replaced the entire thing with one of those plastic constructions. To be fair some kid managed to get a skull fracture on the plastic thing so maybe making things more obviously dangerous is safer. Tangentially related: ask your neighbourhood woodworker how he lost that finger. Good chance it's from the bandsaw, which is a relatively slow moving machine so it seems safer than e.g. a circular saw while in fact the inverse is true.
