A very light, monoline slab serif with crisp, unbracketed terminals and a distinctive faceted geometry. Curves are often rendered as chamfered, near-octagonal forms (notably in C/G/O/Q and the numerals), giving the design a constructed, engraved feel rather than a smoothly drawn one. Stems are thin and even, with small square slab serifs and occasional pointed or tapered join details that sharpen diagonals and corners. Proportions are fairly restrained with clear, open counters; the overall texture is airy and precise, and spacing reads slightly generous in running text.
Best suited to display and short-to-medium text where its faceted curves can be appreciated—editorial headlines, museum or gallery materials, packaging, and branding that wants a crafted, engineered voice. It can also work for charts, captions, and technical-themed layouts when set at sizes large enough to preserve the fine slabs and corners.
The font conveys an architectural, technical tone—measured, deliberate, and a bit antique. Its faceted curves and hairline slabs suggest drafting tools, engraved lettering, and early industrial signage, producing a refined but slightly austere personality.
The design appears intended to merge a classic slab-serif skeleton with a geometric, chamfered construction, creating an engraved/drafted look that feels both historical and precise. The consistent monoline rhythm and unbracketed slabs prioritize clarity and structure over warmth, emphasizing a built, architectural aesthetic.
Several glyphs lean into polygonal construction, which becomes especially noticeable at larger sizes and in rounded characters where the chamfers create a rhythmic sparkle. The delicate stroke weight and small serifs reduce robustness at very small sizes, but the consistent geometry keeps headings and short lines looking orderly and intentional.
