Both saddles have about the same shape and dimensions, but the knife has less padding and the rails are about 1/2 inch closer to the top of the saddle. The spoon has a sticky swede type surface that grabs a bit at your pants, whereas the knife is a more of a smooth textured leatherette with little divots to keep your butt from sliding around too much. I find the spoon more comfortable when riding in jeans or cargo shorts in a more upright stance, such as with risers and the knife better with padded lycra bibs and riding in a more aggressive bent over position on drops or the tips of horns. In fact, I just swapped the knife on my Leader, which I changed from road drops to risers, with the spoon I had mounted on my Dolan, which has road drops with hoods. So, I'd say the spoon is more of a touring/commuting saddle and the knife is more of a race saddle.
