I don't have the materials close at hand to make one right now...unless I sneak into a neighbors yard and cut up their stuff...
..but bonus brownie points if anyone can name that joint y'all are using on these hooks.
Be back later with the answer.
Hint: It's a timber framing joint that was first widely used in shipbuilding. The USS Constitution has a number of those joints in her framing as well as her keel and they are still tight to this day.
Gryphon,
You didn't come back to tell the name of the joint,& no one else tried to answer you, except for my "Clue" answer in the post I quoted below. So, I am going to say my answer would be a "
tenoned scarf joint" . At least that is what I call them. The "scarf", was the clue about what you can wear around your neck.

Is that what you call them? Or , do you have another name for that joint. I have found that sometimes different parts of the region, country, and around the world, have different names for the same thing sometimes. I'd be curious to hear about it, if you have another name for it.
We always called it a "(Clue=item you can wrap around your neck)joint".
Don't know if that is too much of a clue, but I could type the name, but I will wait for others. I have been doing carpentry as a business for some time, & found that different regions of the country call things different names.
But That is what I think most folks call that type of joint/joinery.
I will wait to see if I am gonna get corrected.
