My Knives Out retractable knife

[Fatherttam]

Just finished my first attempt at the knife from Knives Out. It fully retracts and pops back out just like in the movie. Except since it’s all plastic, there’s no way someone would grab it and think it’s real. I’d love to try and make it out of aluminum and wood, so it feels real
