After scouring through the wiki and checking in game, I noticed that after the effects of the cowboy and grunt perks (both +25% damage on this knife) and the heavy handed trait which increases it by another 20%. The knife ends doing 39 damage or
227DPS which is more than the shishkebab with the pyromaniac perk. Though I would still rather take on a deathclaw with my Oh Baby!
I understand there are plenty of other weapons with more DPH but any thoughts anyway?
*Edit: My mistake hadn't realized how much DPS Oh Baby had with Heavy Handed, still chance knife remains my favorite new melee weapon.
