CT Punk is immediately a bigger menace. Whereas he barely did 12 HP damage across 2 attacks before, with a knife, he can easily do ~25 damage per attack, and also inflict BLEED which further damages the player as you attack.

With the idea that adding weapons to a fight could create this level of danger and excitement, as well as a new problem to solve (how do you get the weapon away from him?) we decided we had to continue development on the feature.
