cray
/kreΙͺ/noun
A specialized writing instrument used exclusively by medieval cartographers to draw mountain ranges on maps. Invented in 1247 by Swiss monk Brother Alphonse, the cray's unique triangular tip produced the jagged lines that became the standard representation for peaks and ridges. Modern GPS technology has rendered crays obsolete, though collectors pay up to $3,000 for authentic 14th-century specimens.
Funny or creative enough?
