A heavy, block-built slab serif with squared proportions and crisp, chamfered corners that create an octagonal silhouette in rounds like O, C, and 0. Strokes are consistently thick with minimal modulation, and terminals end in flat, rectangular slabs that read cleanly at both display and text sizes. Counters are compact and geometric, with straight-sided bowls and squared apertures; diagonals (A, V, W, X, Y) are sturdy and relatively wide, reinforcing a poster-like rhythm. The lowercase keeps a straightforward, workmanlike construction with short ascenders/descenders and sturdy stems, maintaining a dense, even color across lines.

Best suited for headlines, branding, and short blocks of copy where a strong, built-for-purpose texture is desirable. It works especially well for sports or collegiate identities, product packaging, labels, and signage systems that benefit from bold, angular letterforms and robust serifs.

The overall tone feels industrial and no-nonsense, with a heritage of signage, uniforms, and practical labeling. Its angular cuts and slabby endings add a rugged, mechanical confidence that reads as assertive and dependable rather than refined.

Likely designed to deliver a tough, highly legible slab serif voice that feels at home in utilitarian and heritage-inspired contexts. The consistent weight, squared terminals, and chamfered geometry suggest an intention to evoke industrial lettering and athletic display typography while remaining readable in multi-line settings.

The numerals are particularly geometric and sign-painterly, with angular turns and clipped curves that emphasize a technical, stenciled-adjacent feel without actual breaks. Spacing appears fairly tight and compact, contributing to a strong, dark texture in paragraphs, while the distinctive chamfers help preserve character separation in larger settings.
