Review on Knipex 0208225US 9 Inch High Leverage Combination Tool by Nick Atkinson

I work in an office and I know very little about electrical work but I do a lot with my own hands. So I was asked to demonstrate a wall at work which didn't seem to be a problem. I removed the first sheet of drywall and unplugged the incoming wire, since it provided power I assumed the rest was safe. Then I cut another wire coming out of the socket. bam! The sparks exploded and he melted a piece of the edge. I have no idea what tension shot through him, but I'm glad it didn't shot through me. They should be great for any professional electrician or anyone who is "special" like me.
