Pickaxes are tools that allow the player to obtain resources. All pickaxes share size and speed, with damage, gather/hit, and sprites change as they are upgraded. The Pickaxe is the most used tool in starve.io, acting as the means to obtain resources. While upgrading a pickaxe does not affect its speed or size, it does increase the amount harvested every hit. In late game, some players prefer to upgrade the pick last-- resources hold a maximum amount of materials and increasing the gather rate does not increase the total gather amount.
