A single-use flint and steel! (the Better Than Wolves! mod was my inspiration)
You can craft it the same way you craft a flint and steel, but instead of a flint and an iron ingot, you use sticks.
You can see it being crafted and used near the end of the video.
Note : If you do not see a custom texture on the custom flint and steel, make sure you have either Optifine, or CIT Resewn if you are on Sodium!
This is my first datapack (and probably last, I hate the weird way you have to make shapes in recipes, took me a good while to figure out), so I hope you like it!
