Serrated edge sharpening tool
Posted: Sun Nov 23, 2014 8:56 am
In my experience and opinion the DMT aligner setup with serrated edge sharpening rods is the best. In my experience I repeat. It controls the angle and direction of stroke and the rods are the same quality as other DMT products. They come in coarse, fine and extra-fine grits. I have the coarse and fine grits. I don't have any EDC serrated edge knives. The only serrated edge knife I have is a bread knife in the kitchen. The only thing I use this DMT set is for sharpening notches that I want a little large as well as sharp inside the notch. I used it on the bread knife a few years ago and it works great. You need to slide the blade clamp along the blade on longer blades. I think you would want to move the clamp every 3 or 4 serrations or so. Here is a picture. The sharpeners come in a folding handle. They unscrew and then screw onto the rod needed for the aligner clamp.
Here's a picture of a knife in the clamp and the sharpening rod close to the position for sharpening.
Here are pictures of the sharpening notch I sharpened on the Techno. There is already a notch on this knife but it is ground flat. I prefer them sharp inside for some things. I don't like a string getting caught in the notch when it's dull. I also have used these notches for cutting the insulation on electrical wires.
Here's a picture of a notch on my new ESEE IZULA II. There is no notch on this knife out of the box. I've come to like sharpening notches on all my knives.
Cost? I think the clamp is about $10 and the rods w/handle are about $21 each. I got the coarse grit rod because the sharpening notches I create need a lot of steel removed. If I were sharpening serrated edge knives I wouldn't need the coarse rod. Fine and/or extra-fine would be good. One thing about this setup is I don't think the DMT rods will get inside the smaller Spyderedge serrations. The tip of the rod is 1/16" in diameter. The size of the serration determines the area of the rod you use.
On knives I want a very small sharpening notch I use a triangle shaped needle file. These also can create a notch that is sharp inside. These files can be used instead of the DMT setup but they will take a little longer and you have to control the angle manually. IMO the angle on sharp sharpening notches isn't that important regarding accuracy. The aligner system has approximate angles based on how you set it up. I'm getting off topic as usual. This thread is about the DMT aligner for sharpening serrated edges. The sharpening notch is just the only thing I use if for since I don't use serrated edge EDC knives. For anyone with questions about different methods or tools for sharpening serrated edges this one deserves consideration IMO.
