A slab serif with squared, chamfered corners that give many bowls and curves an octagonal silhouette. Strokes are largely even in thickness, with bold, blocky serifs and flat terminals that read as machined rather than calligraphic. Counters are fairly open and geometry is tight and regular, producing a crisp, stamped rhythm; joins and diagonals stay angular, and round letters like O/C/G appear subtly faceted. Numerals follow the same cut-corner construction for a consistent, sign-like texture.
Best suited to headlines, posters, signage, and packaging where a rugged, engineered voice is desirable. It can also work for logo wordmarks and labels that benefit from a stamped or engraved look; for long passages, it performs better in short blocks or display sizes where the faceted details stay legible.
The overall tone feels industrial and workmanlike, evoking stamped lettering, equipment plates, and old storefront or workshop typography. Its angular faceting adds a slightly vintage, Western-tinged flavor while remaining practical and no-nonsense.
Likely designed to merge the solidity of slab serifs with a square, cut-corner construction, creating a typeface that feels fabricated and durable. The consistent stroke weight and repeated chamfer motif suggest an emphasis on clarity, uniformity, and a distinctive industrial texture.
Uppercase forms are compact and confident, while the lowercase retains the same hard-edged construction, which can make paragraphs feel textured and emphatic. The distinctive chamfering is the primary personality driver, so it reads most clearly when sizes allow the corners and slab details to resolve cleanly.
