Spark plug gap gauge

Thanks for the suggestions.

I use that style too, luckily. It skips .018", I use the .020, and I believe we struggle to feel the difference of .002" any way.
Yesterday I purchased a box of these Bosch 3 electrode types. They are a heat range or so hotter than the NGK BP6&7s I have been using in the hope that they will burn off at least some of the oil which sneaks downthe valve guides on my engine.
They are a curse to gap, that single wire tool is the best answer.
