A compact, heavy slab serif with broad, rectangular serifs and gently bracketed joins that keep the forms from feeling purely mechanical. Strokes are thick and even, with squared terminals and rounded interior corners that soften the texture. Uppercase letters are tall and assertive, while the lowercase maintains a straightforward, workmanlike structure with single-storey forms (notably the a and g) and sturdy stems. Counters are relatively tight and the overall rhythm is dense, producing a dark, poster-friendly color that holds together well in lines of text.
Best suited to headlines, posters, packaging, and signage where a dense, emphatic slab serif can carry visual weight. It also works well for branding in categories that benefit from a sturdy, heritage-leaning voice (workwear, tools, food and drink labels), and for short text blocks where a compact, high-impact texture is desirable.
The tone reads as rugged and no-nonsense, evoking vintage utility printing, workwear labels, and industrial signage. Its bold slabs and compact proportions project confidence and durability, with a retro flavor that feels familiar rather than ornate.
The design appears intended as a dependable, bold slab serif with a classic utilitarian feel—prioritizing solidity, legibility at display sizes, and a consistent, workhorse rhythm over delicate detailing.
Serifs are consistently wide and flat, creating strong horizontal accents and a stable baseline. The numerals follow the same chunky, squared logic, helping headings and short bursts of copy maintain a uniform, emphatic presence.
