Again my thanks to everyone for their help in identifying where this knife is from. The grip I just found out is horn and not wood as I originally thought. There is also a very small bolster between the blade and grip. I agree that the curve in the sharpened edge was done by either repeated sharpening / honing or was ground away to remove a broken or chipped portion. Because of its size and overall design I did not think that it was ever intended to be used as a weapon. Just an interesting old knife well worth finding some history on.
