A sturdy slab-serif with wide, assertive proportions and a compact, regular rhythm. Strokes show moderate contrast with mostly straight, square-ended terminals and heavy slab serifs that read clearly at display sizes. Many joins and inner corners feature small notches and cut-ins that create an ink-trap-like, slightly distressed mechanical texture. Counters are generally open and round-to-squarish depending on the letter, with a consistent, upright stance and a firm baseline presence.

Best suited to headlines, posters, packaging, and signage where its heavy slabs and mechanical detailing can be appreciated. It can work for short-to-medium text in editorial or brand systems when a rugged, utilitarian voice is desired, but the textured joins may feel busy in very small sizes or long-form reading.

The overall tone feels industrial and workmanlike, evoking typewriter and early mechanical printing aesthetics. Its chunky slabs and intentional corner cut-ins add a rugged, slightly vintage character while staying clear and legible. The impression is confident and no-nonsense, with a hint of retro utility.

The design appears intended to deliver a robust slab-serif voice with a distinctly mechanical, print-worn edge. The combination of wide proportions, strong serifs, and corner cut-ins suggests a focus on impactful display typography that still maintains clear letterforms and a consistent upright structure.

In text, the repeated corner notches and dense serifs create a lively, gritty color that can feel darker than a typical slab at the same size. The figures are bold and simple with strong top-and-bottom structure, and the uppercase carries a particularly commanding, poster-like weight distribution.
