I am not the best at keeping a angle when it comes to sharpening. I have been using a lansky system and am somewhat pleased with the results but it is not the most comfortable system in the world to use. It also takes quite a while the reprofile edges. I am thinking about getting an edgepro. For those of you that have on how well does it work on 3" - 4" blades? I have primarily all folders in this range. also will the edgepro give you a nice clean factory looking edge? I don't want to ruin any knives. Also have you guys been able to reach "Scary sharp" levels with this system?
