A straight tungsten alloy dart barrel features uniform cylindrical outer shape, constant axial cross-section diameter, center of gravity evenly distributed at palm center, providing linear grip and balanced power foundation. Tungsten alloy high density achieves sufficient mass in simple contour, binder phase uniform ensuring consistent mechanical response. In grip, fingertips naturally wrap along axis, pressure points dispersed, suitable for three-four finger universal grip, wrist neutral position. During throw, straight linear structure guides smooth kinetic transmission, release posture convergent, flight yaw minimal, board entry angle stable. Processing from isostatic pressing mold presetting straight cylinder, liquid-phase sintering cooling controlling axial consistency, five-axis lathe synchronous precision turning outer circle end faces, surface laser ring knurling or spiral grooves, providing continuous anti-slip. Coating physical vapor diamond-like carbon film covering, ensuring sweat-dry self-adaptation. In application, straight suits beginners building muscle memory and professionals pursuing pure trajectory, internal embeddable gradient cavities micro-adjusting center without altering shape. Compared to complex structures, straight aerodynamic drag lowest, suitable for long-distance scoring. Environmental processing scraps minimal, recycling simple. Personalization via texture modularization, knurl spacing matching finger gaps. This straight barrel defines structure classification benchmark, advancing darts from basic to advanced progressive.
