Joe, I don't know what science says about this but I do think serrations will cut when partially dull better but I'm not sure that is staying sharp longer. For some stuff serrations are completely unsuited. I have both. My daily use favors plain edges and I like mine sharp. I still have a bunch of serrated Spydercos but I do admit I haven't mastered getting them as sharp as I can easily get my plain edge knives. I will advocate for the "different tool" philosophy which includes steel types and edge types in my choices so I can say one is more useful most of the time for me but I can't say it's better.
Very interesting comment Mastiff
Well all I can say is that I've put my 440V, SE Native through literal hell and back to where I've had to completely sharpen the serrations on it almost daily when I had that one brutal job I testified about a few times here on the Forum. And even toward the end of the day I was still able to sever a few items that I needed to get the job done. So for me when partically dull I still had fair results with my Spyderedged 440V Native model.
Now Evil D kind of echoes my sentiments because I too am a sharpening fanatic and even if one of my blades gets just a little bit dull or dinged up I get the sharpening tools out immediately. And I can identify with what he says about the "Snag Factor" when serrations lose their optimal edge. But you can still get through many fibrous materials even when they are beginning to dull.
But to respond to both of you guys I still maintain that you can do a lot more with a slightly dull Spyderedged blade than you can with a slightly dull plain edge. Just the other day I couldn't even open a bag of potato chips when I got my M390 Military about as dull as I've ever gotten it. But I did put it through a lot of horrendous cutting chores during that day.
Now I will say that it's a lot quicker to restore a plain edge especially with Spyderco's great tools like the GOLDENSTONE, Sharpmaker and 701 Profiles and let's not forget the DOUBLESTUFF. Because it only took me about a dozen strokes on each side of the blade on the GOLDENSTONE to make my M390, PE Military model shaving sharp again. I still say that there is plenty of raw evidence that says serrations will perform much longer after being somewhat dull by our demanding standards.
