Pocket Mechanica / Surface Notes
The skin
What the finish does: stonewash, blasting, polish, anodize, heat color, patina. How a surface changes grip, light, sound, and the way an object ages in the pocket. Every new note appears here automatically.
-
Raw / As-Machined
The bare machined surface, left without further treatment. On copper and brass it will patina immediately with handling; on titanium and steel it shows tool marks, sharp edges, and the…
-
Patina
The living finish of copper and brass: oxidation from skin oils, air, and time that shifts the surface toward browns, blues, and greens. Not a defect — on these metals,…
-
Heat / Flame Coloured
Colour produced by heating titanium or zirconium — with a torch, oven, or flame — to grow an oxide film on the surface. The same interference principle as anodising, but…
-
Anodised
A controlled oxide layer formed on the metal surface. On titanium and zirconium, the colour comes from light interference in the oxide — set by the voltage applied during the…
-
Polished
A reflective, mirror-bright finish achieved by working through progressive abrasion grits to a fine polish. Maximum visual depth and material presence — polished brass glows, polished copper shines rose-gold, polished…
-
Bead-Blasted
A clean, uniform matte produced by blasting the surface with fine media under pressure. More controlled and even than stonewash, with a consistent grain direction that gives a precise, engineered…
-
Stonewashed
A worn, low-sheen texture made by tumbling the object with abrasive media. The process knocks back the surface uniformly, leaving a matte finish that reads as broken-in from day one.…
-
Distressed
An intentionally aged or worn look, applied by the maker rather than accumulated through carry. Scratches, dings, and worn edges are put there on purpose — the aesthetic is rugged…
