Karst

Karst is a geological term. It describes a type of landscape formed when soluble rock, usually limestone, gets slowly dissolved by water, leaving behind sinkholes, caves, and ridges. The word came into English from German, which borrowed it from the Slovenian "Kras," a rocky plateau near Trieste.

Stone is the whole story with this brand, so pulling a word from geology isn't incidental. The name reaches into the science of rock rather than just the material. That's a narrower, more specific choice than something like "Stone" or "Rock" would have been, and it reads more considered for it.

Karst starts hard, a K that stops the mouth before anything else happens, then opens into a soft AHR and a quiet closing ST. There's an odd fit worth noticing, a name for a kind of limestone landscape sitting on a notebook made from crushed stone, so the sound is doing more than decoration. The one snag is the cluster at the end.

RST asks a little more of the tongue than most product names bother to, and someone hearing it cold might land on "carst" before landing on the right letters.

Done with notebooks that bleed ink through to the back of every page, this buyer has finally decided to fix the problem. Sustainability credentials are not the primary reason for the purchase; the search is for a notebook that performs, with the stone-paper story offering something to say when someone asks about it at the desk. This is the person who already buys good pens and has opinions about paper weight, but hasn't found a brand that treats the notebook itself as the product rather than the filler.

A notebook in the range where good stationery sits gets bought without much deliberation if it solves the bleed-through problem and doesn't look like it came from a health food store.

A notebook made from stone paper needs a name that earns the higher price before the buyer reads a single spec. Karst does that.
