I'm currently using a set of Spyderco Profile rods which I've had for several years. My problems are 1) they seem to clog up awfully fast 2) they're not real good for big knives 3) I'd like to be able to achieve a more consistent grind angle for reprofiling blades that are thick-edged. I'm wondering what people prefer for putting a good edge on knives. Will diamond stones resist clogging better than the ceramic rods? What brand/size of diamond works well? What grits? Does anyone have any experience with the Skarb system (looks like a good idea)? How does it compare to Lansky, EdgePro, etc? Thanks in advance for any suggestions and advice.
