With a safety razor I get way more cuts, bumps, and the occasional slice of my thumb... and I'm still tossing the blade. With multi-blade cartidges, I shave faster and with less pain for only marginally more waste (and much greater cost, though trivial).

It’s not so much about tossing the blade, it’s about tossing a blade made mostly from plastic.
