Encyclopedia Robustica: Damage values and why they matter...

[GorillaMyDreams]

The butcher's knife does little damage initially because the majority of the damage dealt is the bleeding over time damage. All you really need to do is stab them a few times and they'll be in crit in no time.

Also, throwing the knife with a successful hit results in instant knockdown, major instant damage, and stun time.

Also, the red chainsaw is instant knockdown as well.
