I like serrations sometimes. I have a lot of EDC knives with serrations that I'm happy with.
Spyderco and CRKT have good serrations. I have a few SOG Autoclips with different serrations depending on the knife - some REALLY good, some just OK. My Benchmades have different serration patterns depending on the knife - but they're all about medium aggressive. Cold Steel has INTERESTING serrations and they're quality is debateable.
Personally, I've always liked CRKT's "triple-point" serrations. They've been consistant throughout their line. I've used the hell out of them and have never felt like I've had to re-sharpen them.
One of my favorite serrated knves of all time is the Benchmade Ares with a half-serrated blade. It has REALLY NICE serrations that has served me well for a long time.
HERE'S THE TRICK to seeing how good serrations are:
Turn the knife over because the serrations might LOOK good on the side they're ground, but once you turn the knife over you'll see that on MANY of them the serrations aren't NEARLY as aggressive as they look on the ground side. I have a couple of Microtechs and cheaper knives that when you turn the knife over I can plainly see that the serrations are shallow and not much different than the plain part of the blade.
Good luck. Do us a favor and keep up with the thread and let us know what you discover yourself.
