I received a KME a couple weeks back. For the first time last night I had some time to get serious with it. I spent a couple of hours sharpening old broadheads to give me a little practice on technique and to just figure the thing out. After my final pass on the last stone I could tell the heads were right on the edge of being hair popping sharp, but I couldn't get them their with just the stone. I am sure with more practice I will. However, I pulled out my leather strop and used the KME sharpener to run the heads a couple of passes over the strop and BINGO!! I got some major bald spots on my arms and legs. I finally had to quit shaving my arms cause I was going to get questions. The heads will plow hair after I put them on the leather strop. I am still going to work with getting them this sharp with just the stones but I can't imagine it would hurt to put them across the leather strop a couple of passes as a final step.
