This treasure chest transported from Manim held quite a few useful items.
[Black Iron Round Leather Knife: Sturdy Wood x1, Cast Iron Block x1]
(Description: A mature and dependable leather crafting tool capable of increasing leather production efficiency.)
So, it's a leather crafting tool.
From the description, it can enhance leather production efficiency.
It seems like quite a practical tool.
Let's move on to the second item.
[Black Iron Curved Battle Axe: Wood x2, Cast Iron Block x2, Metal Parts x1]
(Description: A heavy battle axe that boasts more destructive power during strikes.)
A green-colored battle axe.
Although it's a new blueprint, it doesn't offer much help to Fang Hao.
The axes equipped in the territory were acquired from the Bronze Bull—the "Chopping Axes"—which are also green-tier and comparable in quality.
Plus, the equip rate of axes remains low.
There's no reason to replace the current Chopping Axes with the Black Iron Curved Battle Axe.
