Hey guys, so I was just wondering if this is user error or if my expectations were just too high. I recently got a serrated Dragonfly 2 FFG with VG10 steel, and I was expecting it to be much better at cutting cardboard and zip-ties than my PE, hollow ground knives. I didn't notice any advantageous though, and was wondering if maybe I was cutting the cardboard the wrong way to maximize the serrations? Same thing with zip-ties. That being said, my skyline was razor sharp when I was comparing them. Am I doing something wrong, or were my expectations just too high for the serrations? Maybe the dragonfly would have done worse than it did if it was not serrated, and I'm comparing apples to oranges because of it's smaller blade length? Also, I was wondering if you guys can cut paper with each individual serration. I can, but sometimes not very cleanly. Sorry for the rambling guys. Any suggestions?

I've noticed in my experiences with VG10 is that cardboard kills the edge really quick, regardless of the edge being serrated or plain edge, toothy edge or finely polished. Cardboard has all kinds of junk in it, paper dirt, synthetic fibers, metal pieces, rock pieces, fiberglass pieces, etc. It's not all the same standard cardboard.
I like fully serrated edges because they provide an excellent and very sharp cutting edge for a long period of time, at least those are my observations. Oe other thing to note, Spyderco serrations are chisel ground. This means the edge angle is much lower on those than a plain edge knife. The lower the angle the quicker you can get deformation, rolling, edge damage in general; if the VG10 was much harder you may see some microchipping, but it's treated in such a way that it should roll and deform rather than chip out.

So serrations won't actually help me cut through cardboard??I thought that was the major plus of a serrated edge.
Again, it all depends on what kind of cardboard you are cutting. Double walled and triple walled cardboard is hell on any knife. A few years ago we got about 8 full sized copy machines for several offices. They came in 2x & 3x cardboard. I had a hard time breaking it into pieces with a Stretch in ZDP, Para2 in S90V, and a couple other knives. The blades were really hot to the touch after a couple minutes of cutting. The serrated Para2 I used took a beating.
