大马士革钢砍刀的超写实3D渲染，配OpenAI结形柄头

hyper-realistic 3D render of a tactical Damascus steel machete with a single ergonomic handle. The handle flows seamlessly into a 3D-sculpted pommel shaped exactly like the interlocking-knot OpenAI logo: a continuous steel ribbon of uniform thickness weaving under and over itself in six symmetrical lobes to form a circular knot - no separate end cap or extra geometry. The broad blade displays classic Damascus wave patterns and a mirror-polished finish. Illuminate with dramatic forge-style lighting to accentuate the folded-steel texture and crisp edges. Avoid fantasy elements; show one true machete with the knot-shaped steel pommel as its integrated end.
