As a retired Gunsmith and Machinist, it makes me shudder every time I see someone use the wrong size screwdriver, particularly on a slot head screw. Made a lot of money replacing buggered up screws on guns because folks couldn't be bothered to use the right hollow ground screwdriver the fit the width, length and depth of the screw slot.
instead they used whatever tapered flat blade screwdriver was handy (those were made for opening paint cans, so the Master Tool and Die maker and the Master Gunsmith who taught me those trades both said!) and then wondered why it slipped and buggered up the slot.

I have one of these lighters, available for about $10 on Amazon, handy little guy. I don't smoke, never have, but it is handy for smoking gunsights at the range, etc. and takes up no space in a pocket.
