Practicing Loop, Perfect Enough?

My DIY electrical book says there must not be any nicks or scratches from needle nose pliers when making loops in wire for grounding screws. My pliers must be really crappy because they make the copper look all torn up.

Instead I'm using wire cutter/strippers, with the loop forming holes, and I've perfected it to the point where I can get a good size loop with just one tiny mark. There is one impression on the inside of the loop from where it bends around the tool. Just a line, I wouldn't call it a scratch. Is this good enough? I want to be happy with this result, but perfectionism keeps tripping me up.

You are being too particular.

I think what the book means is that you shouldn't use needle-nose to strip the wires, because that often leaves a big gouge or partial cut in the copper. As far as looping goes, needle-nose are fine just don't smash the copper flat. Surface scratches are not a problem. Copper is so much softer than steel it would be impossible to use a steel tool without leaving some mark in the copper.

Consider what happens to that copper wire when you MASH it under a screw!!!!

A few years ago an older gentleman gave me a screwdriver with a small pin in the handle, for making loops, it worked great. since then It has gotten lost, and I was curious if anyone still makes them?

Go to your local electrical distributor and look at the Kline brand. They make the screwdrivers you are looking for, and they are indeed very handy.
