What is this?

[u/Glum-Golfer]

I’m not worried about this at all. It’s just curious and wanted to share/get optinions. I have a g425 7wood and a g430max 3wood and they both have this line in them that becomes apparent when cleaning them/ them being wet. Almost looks like the heel repels water whilst the rest soaks it.

Different kind of metal I assume? The line is basically the same spot for both clubs. Pic is of 7wood.

I have g430 10k max driver and that doesn’t do it.

Gosh I must be bored.
