Your first night in Minecraft, then the first 10 hours
Swap it at once for a Stone Pickaxe, then make a Stone Sword and a Stone Axe.

The Stone Axe is an axe: the tool that cuts wood fastest, and a heavy weapon that hits harder than a sword of the same material but swings slower. Its head can be cobblestone, blackstone or cobbled deepslate. With 131 uses it already hits for 9 damage, more than an iron sword, at a slow swing. It works like every other axe; the Iron Axe page explains stripping, scraping and shield breaking.
It is made with the Crafting Table from 2 × Stick and 3 × Cobblestone or Blackstone or Cobbled Deepslate.
3 × Cobblestone / Blackstone / Cobbled Deepslate + 2 × Stick → Stone Axe
// Slots with several items cycle through every accepted option.

At the Crafting Table: 2 × Stick and 3 × Cobblestone or Blackstone or Cobbled Deepslate give 1 × Stone Axe. It can be found as loot in Trial Chambers, Ocean Ruins and Igloo. Sold by Villager: Toolsmith (Novice). Hero of the Village gift: Villager.
It chops wood fast, strips logs, scrapes copper and disables shields, and hits hard as a weapon.
131 durability points: each use removes one, and it breaks when none are left. Mending and Unbreaking can extend it.
No: only one per inventory slot.
