so i just got the sharpmaker, and i cant get a decent edge on a knife with it. i can get it semi-sharp, but not near shaving-sharp. i used to use the lansky crock sticks and could easily get a result with a hair shaving edge. i have watched the dvd and read the manual and read articles on the internet, i just can get it. anyone know of some common mistakes i may be doing? i know about angle consistency and all that from when i used the lanksy system. im lost. thanks.
