Similar evolution with chainsaws, probably not related to interpersonal violence...tho maybe the Texas Chainsaw Massacre movie series was involved.
Chainsaws can kick back if used as a stabbing instrument, in a plunge cut. So regulations developed, and tip guards were added, along with a blade brake lever near the top handle. Osha requirements include hardhats with eye. The current tools are fool proof.
They are not, however, idiot-resistant. People still hurt themselves with them. Eventually the mother-state will require registration and licensing for transfer, possession and operation of chainsaws.
And maybe they will be right. Maybe climbing destinations like Everest and Half Dome should tightly reguwlated and engineered to protect the folks who go there. Maybe the world should resemble a McDonalds Playland: fun, but safe. Until the bullies get there.
