Copper spears are worse than stone spears

Stone spears currently have an attack damage of 2 and an attack speed of 1.3333333730697632. Copper spears also have an attack damage of 2, but have a lower attack speed value at 1.1764705181121826. This is inconsistent with all other copper tools/weapons, as the copper tier is designed to be equal to stone but with higher durability. This issue causes copper spears to be inferior to stone spears, which is counter-intuitive and not offset by the durability increase.

Expected Result: Stone spears and copper spears have identical attack damage and attack speed, with the copper having higher durability

Observed Result: Stone spears have higher attack speed than copper spears with identical attack damage, making them worse despite the copper tier being designed to be stone with higher durability
