I think you're confusing terms. A safety razor exposed no more of the blade than a cartridge razor. I think you're probably referring to a straight razor.
The straight razor incidents were pretty traumatizing, so much blood..
Stay safe <3
Edit: I double checked, it actually was with a safety razor. They don't have any buffer to avoid slicing you up compared to a mach3 or modern disposable razor. Please do be careful folks, they are super sharp and a single swipe can cut you up real good.
