a humble blade that quietly defeats locks, bars, and most of your assumptions about safety

means A fine-toothed saw with a thin, replaceable blade stretched taut in a C-shaped frame, made for cutting through metal, plastic, and bone.

from A straightforward compound of "hack" and "saw." "Hack" is an old Germanic word for chopping or cutting with rough, repeated blows — the same root behind the gardener's hacking and the cougher's hack — while "saw" traces back to a Proto-Indo-European root meaning "to cut" (a distant cousin of words like "section" and "scythe"). Together they name exactly what the tool does: it hacks through hard stuff with a saw. The term emerged with the rise of metalworking tools, when craftsmen needed a name for the blade that bit through iron and steel.
