I like the original stingers alot, but I think I'm going upgrade to some buzzcuts this year. The slightly wider cutting diameter is a plus, as long as it still flys as good, but the real seller to me is the serrations. I know every time I cut a finger on my pocket knife, that the serrated part of the blade is to blame......it seems like serrations never dull. I'm sure they'd saw right throught the cartilage and bone, where a smooth blade may deflect.I think of it this way...how do you cut rope? Onepull with a serrated knife or sawbackandforth witha smooth blade? I know I haven't cutfirstpiece of flesh yet, but it cant be much different!
