I've used the Lansky sharpening systems since they came out and have generally been satisfied. I do not own the KME, but from what I've researched they appear to be an improved Lansky-style system, with the operative word here being improved. Lansky's have pre-cut slots in their clamps limiting your choice of angles to 17, 20, 25, and 30 degrees. This may or may not match up closely with the factory (or desired) grind of your knife/broadhead, meaning you may have some metal to remove. KME's appear to be infinitely adjustable within roughly that range, a significant advantage in my opinion. I have a complete set of Lansky conventional and diamond stones and recently ordered an additional pedestal and T-clamp. I was very unimpressed that the tolerances of these parts were sloppier than my originals with 25 years of use! The clamp wobbles around so badly, I won't use it. (how hard can it be to drill a hole the correct diameter?) I contacted the company and never heard a word. I get the impression that it would probably be a shock to their customer service dept. that sportsmen might buy their products. KME knows its customer base! Ron, aka Sharpster, cruises this site all the time and is more than happy to help you with sharpening issues related to his products or anybody elses, for that matter. That's priceless. I don't have to tell you where my next dollars will be spent. If I've misspoken on anything here, somebody that owns both is welcome to clear it up. Just my 2 cents.
