The knife, as some of you may know, is ass. You walk up to someone, swing directly on them, and sometimes it doesn't even kill them even if you see the blood. Perhaps we should replace it with a better designed melee weapon Edit* This is INCLUDING 1-hit knife failing to perform, not regular.
There's too many of em on the workshop to pick from, and I don't know anything about how to tweak with weapons so I only offer the idea, not a solution.
Well, you should know that M9k itself has plenty of Melee weapons, including a couple swords. Theres also this Katana swep that could do 25 HP damage but swing fast https://steamcommunity.com/sharedfiles/filedetails/?id=467523611 A Master sword, swep that could do 50 damage but could play the legend of zelda item get theme when pulled out to warn players! Literally look me 5 minutes but sure...
