the.com/blade
a line so thin it stops being matter and becomes intention
means A flat cutting edge of a knife, sword, or tool — or by extension a slender flat thing like a leaf of grass, an oar's paddle, or a propeller's wing.
from From Old English 'blæd,' meaning leaf, blade, or shoot of a plant — the same word stood for grass and for greenery before it ever meant metal. It has Germanic cousins: Old Norse 'blað' and German 'Blatt' (leaf, page). The thread that ties the leaf to the knife is the shape — something broad and flat that thins to an edge. So every steel blade is, etymologically, still a leaf.
