I have a little exper. with MD's ceramic. I have never gotten hair shaving razer edge on mine... but you don't need one. The knife cuts like a razer on everything but hair. My MD, is a EOD, and its a beautiful tool, but not for everyone. It took me forever to dule the thing. I was wanting to see how well it would sharpen with my Edge Pro sharpinging system ( I got some E Z Lap diamond honds for it) It sharpened right up but You have to be careful... Ceramic doesn't make a bur the way steel does. So you must keep your strokes equal and you must us a 600 to 1200 grit diamond stone. The knife is tough, but a little brittle. A razer sharp edge will make it more prone to chipping out. The edge it came with was all I could ever need when it comes to cutting just about everything.
If you get one just remember Its Not Steel!!
