A heavy, block-driven sans with squared proportions softened by large rounded corners and frequent chamfered cuts. Many glyphs feature small internal notches and slit-like apertures that create a stamped or routed look while improving separation at joins. Curves are built from rounded-rectangle geometry, keeping bowls and counters compact and uniform, and horizontals/verticals maintain a consistent, monoline feel. The lowercase mirrors the uppercase’s chunky construction, with short ascenders/descenders and simple terminals that preserve a dense, poster-ready texture.
Best suited for short, high-impact settings such as headlines, posters, event graphics, sports identities, packaging, and bold logo wordmarks. It holds up especially well when set large, where the corner rounding and internal notches become clear stylistic features.
The overall tone is loud, tough, and functional, evoking machinery, sports signage, and late-20th-century display lettering. Its rounded corners keep it approachable, while the sharp cut-ins add a technical edge that reads as engineered rather than handwritten.
The font appears designed to deliver maximum visual weight with a geometric, rounded-rectangle backbone, while using strategic cut-ins to add character and keep dense shapes from collapsing into solid blocks. It prioritizes bold presence and a distinctive industrial rhythm over subtle text neutrality.
The design relies on distinctive cut details (seen in characters like E, S, Z, and several numerals) that become a recognizable signature at larger sizes. Counters are narrow and openings can be tight, so spacing and size will strongly affect clarity in longer passages.
