The Switchblade Knife Fidget (sharp free) is a plastic, non-functional fidget toy designed to showcase an out-the-front sliding mechanism without any blade or sharp components.
This model is intended for fidgeting and mechanical curiosity only. It features an ergonomic grip for comfortable handling during extended use, making the sliding action smooth and satisfying while remaining completely safe.
To improve comfort and usability, two versions are included:
- Right-handed model
- Left-handed model
No cutting function, no metal parts, and no weapon use — this is a toy/prop only, designed purely for safe desk play and mechanism demonstration.
Recommended materials: PLA or PETG
Difficulty: Easy
Supports: Not required
Great for: Fidgeting, desk toys, mechanism demos
