This is a concept for a new weapon idea for Minecraft's combat system: The knife! Though it is weak and still as slow as a sword, its special functionality makes up for it. Critical hit multipliers! The wooden variant of the knife deals 2 attack damage, but it has a 2x damage multiplier when you land a critical hit. Each knife tier not only increases the damage you deal but also increases the multiplier.

Both stone and gold deal 3 damage and have a 2.5x multiplier.

Any tier after stone no longer increases attack damage, only the multiplier.

Iron has a 3x multiplier

Diamond has a 4x multiplier

Netherite has a 5x multiplier.

This weapon cannot use enchantments like sharpness, bane of arthropods, or smite, but it has one new enchantment exclusive to the knife. That enchantment is called Quick Sweep (I'm bad at names, okay?).

Quick sweep makes the cooldown time of each attack from the original 0.625 seconds down to 0.285 seconds!

So that's my new Minecraft combat weapon idea!
