'Crazy'.... call me crazy but go run a quad port saw, they all smell very similar. Dual port saws seem to smell harsher, strato saws seem to be the best. And echo top handles all smell very similar...
But it does sound like a game show idea: take you into the woods, blindfolded and with ear muffs, and have you ID running saws by smell. Miss it, and we drop you in a big bowl of Jello.
