Create a detailed 3D model of a short steel spear with a polished blade and a matte shaft. Carve a spiraling band of glowing runes around the shaft, with subtle markers at the beginning and end of the spiral. Finish the pommel as a simple steel sphere. Apply realistic metal materials plus emissive effects for the runes.

Use a dark charcoal-gray steel shaft with micro-pitting normal and abrasion scratches. Roughness 0.80 overall, 0.60 in grip; Metallic 1.0. Engrave a 4.5-turn spiral of runes (1 mm deep, 6 mm wide). Emissive map: soft red glow pulsing 15–30% with 2 mm halo; Specular ~0.9; Height/Normal maps capture 1 mm depth, 0.5 mm ridges, 1 mm fillets. Spearhead: deep gunmetal tone, Roughness 0.15–0.25, 5% micro-scratch overlay; Metallic 1.0. AO map accentuates shadows in grooves and edges.
