What is it? Weekend Edition 6

Looks a LOT like the hand screws I use to attach my tree stand to the tree. They go through drilled holes in the frame and into the tree. The T is usually dipped into handle dip to provide some protection.

This is a newer version

I haven't found any pictures of compartmentalized tobacco boxes, but there's a guy who wants one:

Nowadays, pipe tobacco is often sold in foil pouches. It costs more that way, and it has additives to keep it fresh. It still loses flavor rapidly in a pouch, and it's hard to load a pipe from a nearly empty foil pouch.

Tobacco from a fresh can tastes better. It's easy to fill your pipe because you can see what you're doing and spilled tobacco falls back into the can.

A can may contain more than 200 bowlfuls. If you open it that many times, it will lose flavor. Also, when filling from a can you can't keep track of your daily usage. If you smoke more than half an ounce in a day, it won't taste good the next day, and you may run out a week before you can buy more.

I transfer my tobacco to an empty can half an ounce at a time. The mystery item would hold a week's worth of half-ounce rations. If the compartments are not all empty at the end of the week, you can fill the empty ones and keep moving clockwise. The diameter is bigger than a can, so you won't spill on your desk. Thick wood seems like a good idea for a tobacco box because you can add humidity to the wood to keep the tobacco from drying out.

I've seen something vaguely similar for holding lead fishing weights. This for example:
