I've read everything I can find about the subject of pastes. There's one thing I'm not sure of still. Most pastes, it seems, help refresh an edge by smoothing out the very edge of the razor. They don't "cut" into the steel and therefore don't increase the bevel length as honing does. Eventually pastes don't work and the razor much touch a stone. My question is, are diamond pastes and sprays an exception to this? Because diamond is hard and potentially does more cutting, does it in fact lengthen the bevel like a stone? OR, is it less the paste used and more the motion used in honing that effects this (ie. because you hone with the edge leading, this is what truly cuts and lengthens the bevel)?
