the.com/blowpipe

means A narrow tube used to shoot darts or pellets by force of breath, or a jet-tool for directing a flame or air blast in metalwork.

from Simply 'blow' + 'pipe' — a straightforward compound describing exactly what it does. The weapon form is ancient and widespread, independently developed by hunting cultures across South America, Southeast Asia, and elsewhere; the English word itself dates to describing the tool rather than naming any single origin culture. The term later extended to the glassblower's and metalworker's blowpipe, which directs a thin, forceful stream of air or gas into a flame to concentrate its heat.
