Sent my Benchmade/Bali-Song Mini AFCK with half serrated blade back to the fatocry for sharpening (actually, handed it to one of the techs at the Benchmade booth at SHOT). Got it in '96, IIRC. New, it was scary sharp. EVERYONE who touched the blade ended up bleeding. It would seem that the fatocry can no longer duplicate that, as it came back with a normal type of sharpness. What is annoying is that they reassembled it back to the original right-handed clip position, discarding my custom length button head screws needed to mount it for left-handed carry.All my carry knives are modified for improved access for left thumb opening. Basically copying as close as possible the right-handed thumb cut-out.My heavy use knife is a CRKT Point Guard, carried for right hand access. Got it for cutting away bumper covers of crashed cars, so they could be driven. Slightly shorter now, as the tip broke off when I tried to straighten it when bent. Don't remember bending it. Half serrated.Got a cheapy little Barracuda half-serrated liner lock that lives in one pocket. For opening food containers, or other light-duty use.Leatherman Micra lives in the other pocket. Very sharp blade. Needs two hands to deploy. Only straight blade I currently carry.Have one of those Swiss+Tech Utili-Key tools on my key ring. It is a half-serrated blade. Can't remember it being used. Back up back up blade, I guess.I have decided I will not be acquiring any more half-serrated blades for future use. Maybe if I find one with the serrations at the tip end. I have decided they are not very useful. They just get in the way of most uses for a knife. The true value of serrations is to keep a sharp cutting edge after running the blade against a surface that would dull/damage a normal edge. That is a very narrow job description for a general use knife. Essentially, that is a steak knife job. Which these can't even do, with that saw edge at the handle end of the blade.In conclusion, I would say the real purpose of them is to look intimidating, which is why you weren't allowed to fly with them back before 9/11.
