That's hilarious. I had a set of clubs for a short time without the line drawn under the 6 and the 9. Drove me crazy.
Nowadays it's impossible for me to make that mistake, my 9 iron is a different style of club AND a different brand. I have a 9 iron players blade and a Super Game improvement 6 iron. 9 iron is dynacraft, 6 iron is Tour Edge. I dare say nobody could confuse them.
Played another rusty 18 holes yesterday, but made some good shots along the way.
The best one was on a 370 yard par 4, where I missed the fairway left and dumped the approach in a pond short left of the green. Took a drop and had 85 yards into the wind left to the pin over the same pond, landed it directly in the cup and broke both the cup and the Covid-filler put into it. The hole spat it back out to a 5 inch tap-in bogey, but it was still pretty amazing shot. Wonder if it would've stayed in without the covid-filler in the hole.
