A polygon tungsten alloy dart barrel features four-six-eight faceted cross-section, center of gravity locked at facet finger gaps, providing tactile positioning and spin enhancement. Tungsten alloy hardness equilibrates facet mass, binder phase corner gradient ensuring structural strength. In grip, facets fit finger gaps, pressure locks ridges, rotational grip directional. During throw, polygon facets guide spin, release rotation stable, flight disturbance-resistant, board entry point firm. Processing mold presetting polygon, sintering uniform field cooling, milling machine edge-by-edge processing, surface electrochemical ridge grooves, coating chemical vapor titanium nitride film. In application, polygon suits creative spin and mixed grip, internal positioning cavities facet density enhancing rotation. Compared to torpedo, polygon tactile stronger, suitable for blind throw; compared to wave, static positioning superior. Environmental complexity moderate, waste complete. Personalization facet scanning adjusting edge count, matching finger gaps. This polygon serves as creative pillar, advancing sensory diversity.
