<p>Sharp combines pure geometry and bold structure for a brutalist, high-tech feel. The Line variant offers clean, geometric strokes.</p>

**Summary**: The foundational Sharp sub-style — 2px geometric stroke, square caps, zero-radius corners, monochrome. The set clusters at the serious and authoritative end of the spectrum with no warmth cues present. The tone signals "we built this with tools, not feeling" — engineering notation rather than approachability. Best for primary navigation and toolbars in enterprise software, developer tools, and professional SaaS where icons should serve the interface without leading it.

## Fit & Recommendation

### Primary use cases

- Primary navigation and UI controls in enterprise software
- Dense toolbars and action bars where icons must stay legible at 16–20px
- Developer tools and code editors
- Admin panels requiring neutral, distraction-free icon chrome
- Professional SaaS products where icons should serve the interface, not lead it

## Visual & Technical Specs

| Stroke weight | 2px |
| Fill | None |
| Corner treatment | Sharp / 0° miter, square caps |
| Color | Monochrome |

### Emotional Scores

Sharp Line is one of the colder sub-styles in the catalog — square caps, zero-radius corners, and 2px miter joins carry no warmth cues anywhere. It is among the hardest sub-styles in the catalog — 2px geometric stroke with miter joins is among the harder line styles possible. It is one of the more formal sub-styles in the catalog — constructivist geometry reads as engineering notation, not approachability. It is among the most serious sub-styles in the catalog — no decorative flourish, no curved end caps, no expressive construction. On its human↔mechanical character, it is among the most mechanical sub-styles in the catalog — pure geometric construction throughout makes the compass-and-ruler aesthetic literal.

## Pairing & Compatibility

### Typography pairing

- **Primary**: IBM Plex Sans — shares the engineering culture, grid-first construction, and Swiss precision
- **Alternative**: Neue Haas Grotesk — geometric grotesque at its most authoritative
- **Display**: Space Grotesk — adds subtle personality without abandoning geometric structure
- **Body**: IBM Plex Mono — for developer tool contexts, this is the strongest pairing in the family
- **Avoid**: Nunito, Poppins, any rounded terminal fonts — direct contradiction with the sharp geometric DNA


<p>Sharp combines pure geometry and bold structure for a brutalist, high-tech feel. It’s raw, trendy, and unapologetic. It pairs best with typefaces that have strong construction, such as Futura, Gill Sans, or Space Mono.</p>
