Sharpener

Sharpener is the main antagonist of "No More Mr. Knife Guy".

Orange made a joke that involved saying he was "dull". Knife tried to warn Orange that if sharpener heard him, Knife would be forced into a good sharpening.

Dane Boedigheimer later stores the sharpener behind the knife block.

However, it is unknown what had happened to him in Season 6 (as the kitchen had undergone some remodeling at that time). After the remodeling, the sharpener is no longer stored behind the knife block.

Personality
Sharpener is a knife sharpener with a misshapen face. He is a cruel and ferocious knife sharpener who shows his superiority with cruelty. Knife is very horrified by him as he is a vicious monster.

He has a dark, evil and menacing accent, a villainous attitude, and sharpens any dull bladed knife. According to Knife, he is "harder than a rock".
