Karen Beverly is an extremely detailed plastic toy knife, unlike Forky, despite being a hand-crafted kindergarten toy.
Karen Beverly's only appearance was during a mid-credits scene where Jessie, tells Bonnie's toys that Bonnie made a new friend in class. Showing the toys Karen Beverly, the other toys become shocked upon looking at Forky looking at her. Forky introduces himself to the new toy Bonnie made, just as Karen Beverly doesn't realize herself of how she was alive to which Forky replies, "I don't know."
- According to the audio commentary, her name was confirmed by Josh Cooley and Mark Nielsen during the credits. Josh suggested using the name "Karen", named after Mark Nielsen's sister, followed by "Beverly", also Mark's sister, which is used as a suggestion for the character name.
- The name "Knifey" is colloquially used as an in-joke of many characters in the Toy Story franchise whose names end with a long "E" sound.
- "I think Forky and Karen Beverly have a bright future together." ~ Mark Nielsen
