means A coarse-toothed handsaw designed to cut wood along the grain (with the fibers rather than across them), its big chisel-like teeth shearing the wood as it goes.

from A compound of the verb 'rip,' meaning to tear or split apart — itself of uncertain origin, possibly related to Flemish or Low German words for tearing — plus 'saw,' from Old English 'sagu,' a tool with a notched edge (a cousin of words tied to cutting, like 'section'). So a ripsaw is literally a 'ripping saw,' named for the way it splits wood along the grain rather than slicing neatly across it.
