My battery powered tools are great.
But.
They all have a safety switch, let it go, tool cuts out. All that is, except the angle grinder. It has a safety that cuts out if it jams with blood & bone, but it's on until manually switched off.
I can fit various spinning blades of death, turn it on, drop it, & those death blades will continue spinning through my boots & feet until jammed with blood & bone... All my other tools would cut out before they hit my foot.
Why is it so?
