You will probably get a thousand and one responses about how folks hate serrations and prefer plain edges. I generally fall into that camp, but I find serrated knives also have their uses.
I have a serrated RC-3 and I like the way it performs. Good at doing what serrations are supposed to do, i.e. cut rope etc. To my surprise, the RC 3 was also quite good at wood work and did fuzzies much better than I expected it.
The RC serrations differ from those of other companies like Spyderco. They are sized so that you can sharpen them with a standard 1/8" round file. Alternatively, the sharpmaker works extremely well. Because the RC serrations are wider and flatter, you can even sharpen them on a flat stone. You sharpen them like you would any plain blade. I thought this was hog wash until I tried it. It works, albeit, sharpening them using the corners of the sharpmaker rod does a better job IMO.
Unfortunately, I always make things more complicated for myself then they need to be. So I convexed the plain portion of the edge of my RC-3 and sharpen that part as I would do a convex knife and then sharpen the serrated part with the corners of the sharpmaker.
It is a great little knife and perfectly suited for climbing. The sheath is incredibly versatile. It will do wood work and camp chores if called upon to do so. Maybe not as brilliantly as a puuku, but good enough and effortless enough to not make your regret having it during camping. My RC-3 comes along with me on a lot of trips even though I have a lot of blades to choose from.
