Done it this way 2x already - works well

I've done this kind of repair with a technique similar to what Pat describes - works really good and is easy to do. I used regular epoxy mixed with chopped carbon strands for thickness/filler (had some small pieces of carbon laying around that I just chopped into about 1mm long pieces with simple kitchen scisors). Used 2 halves of a single plastic lid from a disposable food container. Once dry, the plastic just peels off and a bit of filing with a metal file or a sandpaper block to bring the shape back to where it was and it's done. Very easy, actually, and pretty much can't tell where the repair was on my carbon blades... Since it's going to get chipped again some day, and because the rest of the blade already has plenty of scratches, absolute perfection is not needed, so 600 grit sand paper is more than enough to make it disappear to the touch.
