EDC Fidget Toys - Void Sword

### ⚔️ ** 1. Core design: Deconstruction of weapons and Mechanical aesthetics **

1. Innovation in the sword-shaped theme

- ** Hollow Sword Design ** : Inspired by ancient Chinese swords (such as Han swords/Tang swords), it is deconstructed into a foldable EDC size (about 120mm when unfolded and 60mm when closed). The sword body is engraved with "ice crack" or cloud and thunder patterns, and a tritium tube slot is embedded in the sword compartment (guard). At night, the faint light simulates the "flow of sword qi".

- ** Deformation Structure ** : The "scabbard separation" is achieved through the slide rail or bearing. The scabbard body can rotate 360°, and the blade part hides the magnetic attraction card pushing module (pushing simulates the touch sensation of "drawing the sword out of the scabbard").

2. "Industrial Style details

The gear transmission is exposed, and the titanium alloy is CNC-engraved with blade patterns, combining the solemnity of weapons with the mechanical feel of cyberpunk.

### 🔧 ** 2. Decompression mechanism: Multimode interactive experience **

| ** Module | ** Function | ** Sensory Feedback |

| ** Magnetic Push Card ** | There are three hidden push and pull structures (N52 magnet + ceramic beads) at the sword grid, which produce a "click" sound when pushed | Paragraph feeling + sound relief |

| ** Rotating Scabbard ** | The scabbard body is equipped with an R188 ceramic bearing, supporting high-speed rotation like a fidget spinner (idle for 8 minutes) | Visual tracking + tactile balance |

| ** Split Combination ** | The sword blade and sheath are magnetically attached, allowing for separate play or combined swinging (counterweight balance design) | Modular control fun |

### 🛠️ ** 3. Materials and Workmanship **

- ** Main material ** : TC4 titanium alloy blade (lightweight and high-strength) + brass/zirconium alloy sheath (weight optimization), surface treated with stone washing and sandblasting, scratch-resistant and wear-resistant.

** Core components ** :

Silicon nitride ceramic bearings (silent and smooth)

Tritium tube night light system (Sword Grid slot ×2, supporting blue/green tritium tubes)

Magnetic attraction module (thrust 0.8kg, precise adsorption reset)

- ** Safety Design ** : Blade-free and obtuse treatment, in compliance with EDC toy safety standards.
