volcanic glass that snapped into blades sharper than the surgeon's steel beside it
means A dark, glassy volcanic rock formed when lava cools so fast it never crystallizes, prized for fracturing into razor-sharp edges.
from From Latin 'obsidianus,' a name traced to Pliny the Elder, who recorded the stone as 'obsianus lapis' — said to be named after one Obsius, a Roman reputed to have brought it from Ethiopia. A copyist's slip is thought to have turned 'obsianus' into 'obsidianus,' and the misspelling stuck, so the modern word may carry a scribe's error fossilized in its very letters.
