The empty answer
If the factory never cut a hex, neither do we
Golfers ask. We say no. A scoring club lives on bounce, grind, and a loft that was bent on purpose. None of that is a 4 g plug. Drilling a hole in a wedge to make the menu look complete is how you ruin a short-game head for a gram that did not need to exist.
The rare exception is still a factory hole
A few wide-sole scoring clubs ship with a rear screw that is a real thread. If yours has one, Cal will weigh it like any other back socket and decide whether walking mass belongs there. That is still not a drill day. That is a yes/no on a hole that already exists.
Where we send wedge work
Not across our own binder. There are grind benches in this town and in Bozeman. We will name them if you ask in person. We will not pretend Suite 2 is those benches. The honest empty page is part of why the rest of the tray can be trusted.
