What is a good quality budget sharpening system that is similar to the Edge Pro Apex? I would like to re profile the edge on my Cold Steel AK-47 because the relief edge is terrible. it almost looks like it is chisel ground. I would also use this to improve the edges on some other of my knives but i really don't have the money for an EPA or a WE so I was wondering what would get the job done. I would like to keep it under $100 but I want as inexpensive as possible. What are your suggestions?
