Need to discharge my broken monitor as a precaution, but I don't have au wire to attach to a screw driver etc. Was thinking of attaching a car battery lead. Would this suffice if it clamps on the screw driver. I'm guessing yes but please advise if you can see any problems

I have an old flat blade screwdriver that I have wound a long piece of household earthing wire around then all taped up to the handle of the screwdriver.
I only leave the end of the screwdriver exposed, that way the spark can't jump from the screwdriver to my hand (I have had this happen once before making this tool)
The end of the wire goes to an earthing point (away from my hands)
