I see these terms a lot lately and I have to admit I really don't know what they mean. If a blade is sharp (bevel set, edge refined to high grit) then how could it not be smooth and comfortable to shave with? If the blade is super sharp, then wouldn't it just slice through the hairs effortlessly without pulling, and thus be comfortable? How can a well honed blade be "crisp"? What does crisp even mean?
