Most likely some sort of slight smile or warp, your technique may be at fault too. Personally I started off with too much weight on the heel. A good technique is a rolling X stroke. Start your stroke with emphasis towards the heel, as you move down the hone the heel leads but you roll your pressure towards the the toe. Pressure should be just enough to keep control of the razor. Generally less pressure is better with edge and bevel condition dictating how much pressure you need. Search gssixgun on you tube as well as Lynn honing. Between those videos and detailed reports on this thread, you’ll be able to get a good edge without junking your razor in the process.
