This one is a blend of 2 earlier designs. It is curved more than I'd normally do. It came out allright. It is not as curved as those kikuboshi razors I've seen. That would be even more challenging to grind I think. And to be honest, while smiles shave better than straights, there has to be an upper limit to how curved you can make a razor before it starts to become impractical.
