Swap it at once for a Stone Pickaxe, then make a Stone Sword and a Stone Axe.

The Stone Sword is a sword, the standard melee weapon: quicker than an axe, with a sweeping attack that hits several mobs at once. A stone blade, whether cobblestone, blackstone or cobbled deepslate, deals 5 damage for 131 hits. It works like every other sword; the Iron Sword page explains sweeping attacks and enchantments.
It is made with the Crafting Table from Stick and 2 × Cobblestone or Blackstone or Cobbled Deepslate.
2 × Cobblestone / Blackstone / Cobbled Deepslate + Stick → Stone Sword
// Slots with several items cycle through every accepted option.
