Nice! I was going to suggest to bend the nails a bit, but then I saw that the top of your tube is bent. Interesting. I do kinda have to hunker down a little to use my blowpoke; perhaps I do want the end bent.

The fire poker is one of humanity's oldest tools; probably Paleolithic, and likely "discovered" immediately after we learned to control fire, roughly 1 million years ago. A million years of development, and single-prong is still the default configuration.

Now back to my primary life goal: heating a hot tub with my woodstove.
