In view of the fact that the thinner the edge the sharper the instrument, most purchasers of a razor quite naturally conclude that the full concave blade is the best. Our impression is that this is a mistake; that the full concave blade is not so good for shaving most beards as the three-quarters concave. In a very deeply hollow ground razor, the blade is ground extremely thin, back to a line some distance from the edge.
