You may be destroying each edge as you start the other one. Moras have a lot of very minute imperfections. Take a steel or ceramic hone and burnish both sides. Then with the full bevel flush with your sharpening medium work until you have the 'wire' on the full length( the thin fold you can feel.) Then dress the other side until it has one. Then it is just a progressively lighter repetition until sharp. Sometimes the new Moras need a few sessions to reach their potential. Minor temper and grind imperfections are a given with an inexpensive knife. A few sessions usually brings the 'clean' steel out. Some users even use lapping mediums or cardboard for a final strop. Once these are poperly prepped, only the hone is often needed to maintain a edge unless heavily abused.
