Well just as the title says, which do you prefer. My most common carry knife is my old Buck Crosslock with one drop point smooth edge and one fully serrated edge. I see a lot of full size fixed blades that are combo blades with part of the blade serrated and part smooth. To confuse matter more there are two basic forms of serrations, Those with aggressive sharp pointed and those with smooth rounded points. Case in point these two KA-BAR's. One is the modern incarnation of the WWII classic and the other is the companies take on a modernization of the design with a different style guard, pommel, a handle made of Kraton and a blade of D2 steel.
While I do appreciate the benefits of a serrated edge it seems that every brand has a different contour. The only way to really sharpen them with any efficiency that I can see is to sharpen the reverse side of the grind with a flat stone. In order to not mess up this section of the blade you need to be careful while sharpening the straight edge portion. This is because the serrated portion of the blade is almost always ground on one side only while the remainder is symmetrical from side to side. To be honest my first "USMC" KA-BAR I had was the combo blade. I gave it away and bought the smooth edge because the real originals were a smooth edge. In retrospect I should have kept it and should bought the new one but I was trying to be nice to my nephew at the same time.
What is your preference for a blade edge? Do you prefer a straight edge for a fixed blade or a combo? Other thoughts on the the subject?
