Has anyone used an engraving pen to personalize their planners?

I am going to try to recreate my favorite planner and to do list, which used to be sold by Anthropologies. It was called a 'step' planner, and featured two soft-sided books.

The top book said 'to do list.'

The bottom book, on Inch wider but the same height as the first one, stated "Plan Ahead," and had an undated planner with the horizontal week on the left, and a blank page on the right.

This year, I made my own undated planner using a nice Moleskin...and I have a separate 'to do' notebook.

But...it's not the same. They are unattached.

So, my journey for 2027 is to make my own 'step' journal. But I need to engrave it.
