Quoted By:
The primary reason most people don't like serrations is that they are more difficult to sharpen, especially "in the field". However, I also have a partially serratted Mini-Griptilian in scary-tactical-black, and have found that I simply have never needed to sharpen the serrations. I've run a honing rod across them once or twice, but really it was unnecessary to do so as they still cut through cable-ties just fine. Then again, that's more of an occupational situation, I run wire for an alarm company and and use zip-ties almost every other day. I either use my tin-snips or my Benchmade to cut them depending on the angle. I also have a beater knife, a Gerber Remix, never sharpened the serrations in over a year of hard outdoor work on the job, and the serrations still cut. Serrations simply need less care.
For bushcraft though, non-serrated is the only way I could go. Just more practical to have a plain edge when working with wood IMO.
