Serrations

[sja2249]

I've noticed that the vast majority of serrated blades ( and serrated portions of blades ) are single sided. I understand not cutting serrations into both sides, but why do they need to be single edged? I have a few knives that are beveled on both sides but only serrated on one... that seems like the way to go as far as I'm concerned. I have a couple of CRKT Mirages that have some weird inverse serrations, and I have some Gerber SLs that have more traditional serrations but are beveled on both sides. At least with the double bevel I can at least attempt to keep the knife sharp and not have to worry about the transition from single bevel to double bevel.

Are there other examples of knives like these?

Any knife will cut much more aggressively with a smaller angle on the cutting edge. This is why your plastic shaving razors are only sharpened on one side. The same goes for serrations, coupled with the rounded patterns (scallops). Not sure why some companies grind their serrations double sided. It could be an aesthetic, I'd be hard pressed to believe there is a performance advantage, but you never know.

I find single sided serrations easier to sharpen than double cut ones... A few passes on the 1K ceramic hone on the flat unground side works well on these two knives:
