The Chromeworks Filament Series replaces the full arm with a mirrorpolished chassis housing 22 independently actuated micro-servo tendons capable of sub-millimeter positional accuracy, rated to ±0.08mm under load. The neural integration suite uses Chromeworks' proprietary SilkLink feedback mesh, which translates sensory return data with enough fidelity that surgeons report being able to feel the tension differential between tissue types. The arm's external profile is deliberately understated — brushed surgical chrome with minimal panel lines, designed to read as professional rather than augmented.

The Filament is the preferred arm of GLMZ's elite surgical community, high-end watchmakers in the Midspire artisan districts, and licensed demolitions technicians who need to manipulate micro-detonator assemblies without triggering them. It carries a quiet prestige among Tier 3-4 technical professionals — owning a Filament means your hands are your livelihood, and you invested accordingly.
