The small flint from Kin Issei's disposable lighter refill was a ferrocerium alloy. It was overwhelmingly superior in performance, durability, and longevity compared to natural flints.
It was incomparable to expensive flints that needed to be replaced after firing 10 or 20 shots.
It could even create sparks when slightly wet with rain. Whether wet gunpowder would ignite was a different matter, but.
So far, no one knew about this.
They were just happy that the loading speed had doubled compared to existing muskets.
The overwhelming difference would only become clear decades later when the flintlock method was widely adopted in Europe as well.
For now, the knights and apprentices were just amazed.
These were simultaneously supplied to hundreds of Knight Order members? When did they make them so quickly? There's been a lot of noise about building factories lately—is this the result?
"Silence."
