Uncommon items are normally obtained a little later in the game, and are slightly better than their Common counterparts, in both design and usage. Most are obtained in either the First Sea or the Second Sea, and are generally okay for most activities. A notable exception to this is the Twin Hooks sword, which is a sword only obtainable in the Third Sea, and is massively more effective than other Swords of its rarity. This rarity also has the most amount of Elemental fruits.
There are 6 Blox Fruits in this category: Flame, Falcon, Ice, Sand, Dark and Diamond.
Almost all of these have good PvP potential, and the Elemental types are great for grinding, due to their immunity and their high damage attacks.
There are 4 swords in this category: Iron Mace, Shark Saw, Triple Katana and Twin Hooks.
The majority of these are from the First Sea and are weak for PvP and grinding. However, an interesting exception is the Twin Hooks, as it is from the Third Sea and is quite powerful, being comparable to Legendary Swords.
There are 2 guns in this category: Flintlock and Musket.
Similarly to the Slingshot, they are mainly used to gather up NPCS, although the Flintlock can be used for PvP due to its stun move.
There is 1 accessory in this category: Pink Coat.
It is okay for gun-based grinding and PvP. However, its boosts become negligible compared to higher-tier accessories.
There are 10 materials in this category: Bones, Ectoplasm, Fish Tails, Fool's Gold, Gunpowder, Mini Tusk, Mystic Droplets, Radioactive Material, Shark Tooth and Vampire Fang.
However, Gunpowder is completely useless and serves no purpose in the game, whatsoever. Bones and Ectoplasm also act as types of currency, as well as being materials.
There are no scrolls in this category.
