I'm always comparing the feel in my hand of the Reg v/s the SOD. The blades are virtually the same length. The Reg is thicker but the SOD is wider. The balance point of the Reg seems to be about where my index finger rests on the handle. The SOD feels much more blade heavy than the Reg with the balance further forward. The thicker handle with the balance point makes the Reg unbelievably nimble feeling for such a sizable knife. I wonder what the weight difference between the two is...
