Yes.  More than I am, clearly.  Thank you.  It's funny it wasn't with other tools, so whoever packed that box apparently viewed it as a mystery object.

It's a Mortise Guage.

I always called it a marking gauge but it’s a simple tool for precise measurements. 

Hand carved the mortise and tenons on our oak dining room table and the crafting table I made for the kids using one (also inserted a locking dowel / trenail so they’ll never go sloppy)

That's très cool.  As a crude structural carpenter, you folk are like unthinkably advanced aliens to me.  My zen thing is more putting in a window or hanging a door, or electrical.  Anything is zen that is guided by the need to always know precisely where both your hands are,  and that you exist in a bubble of calm quiet.  (I did once make a simple mortise, using 4x4 for work table legs and running 1x4 rails into them.  Where I learned about keeping chisels sharp...)

I’ll be replacing an exterior threshold tomorrow myself so long as the weather holds. Once that’s done, I’ll proceed with laying down new decking on the uneven joists I flattened and graded 

After a few days dangling with my feet ten feet over the ground using sharp tools, they’re even now
