A sturdy slab-serif design with mostly monoline strokes and pronounced square serifs. Curves are frequently simplified into straight segments with chamfered corners, giving bowls and rounds an octagonal feel (notably in C, O, Q, and the numerals). The letterforms are upright with broad, open counters and a firm baseline presence; terminals tend to be flat and squared off, and diagonals are crisp and angular. Overall spacing and proportions read solid and engineered, with a slightly segmented, constructed rhythm across text.
It performs well in display settings where strong structure and high legibility are needed—posters, headlines, signage, and packaging. The robust slabs and faceted curves also suit branding that wants an engineered or vintage-industrial flavor, and it can hold up in short-to-medium text where a distinctive, constructed texture is desired.
The font conveys a mechanical, no-nonsense tone—confident, industrial, and slightly retro. Its angular rounding and bold slabs suggest technical labeling and vintage machinery aesthetics more than literary delicacy.
The design appears intended to merge classic slab-serif authority with a simplified, built-from-straight-lines geometry. The repeated chamfers and squared terminals suggest a deliberate nod to technical lettering and durable, print-friendly forms.
The chamfered geometry repeats consistently across uppercase, lowercase, and figures, creating a distinctive faceted texture in paragraphs. Numerals follow the same segmented logic, with squared corners and straightforward, sign-like silhouettes.
