The latest in the series of videos I've been doing on the many uses of scythe stones. Deburring the backside of conventional serrations is usually the most challenging aspect of sharpening the typical hollow saber grinds found on serrated knives. If you sharpen both sides using the edge of the stone, you thicken your angle. If you use a flat surface, you only deburr the points of the serrations and accelerate wearing them out. The curved sides of a scythe stone allow you to maintain very nearly the same angle as from the factory.
Good stuff! I had a tapered round diamond DMT file that I used to use for serrations. I don't own that sharpener anymore because I don't own anymore serrated blades!
I still have a few things with serrations like my Spiderco Rescue and most of my multi tools have a serrated second blade. I almost never use these but still dread when I have to do anything more than a simple strop touch up.
Glad it's helpful! I've got one on machetes done up but haven't had the time to put it through editing yet.
