I have both and use both. I think I remember having to use it a few times before I got the knack of it.
" use a sharpie to mark the bevel. if you are removing ink from the tip of the bevel only, the stone is too high. if you are removing ink from the back of the bevel, it's too low. this will help you get your angles matched up"
Good advise! I use a set of head magnifiers so I can really get a good look at how the primary stone is taking off the metal. I purposely align my angle at less than 40 degrees, so I can use my sharpmaker in the 40 degrees slots to keep my edge razor sharp.
Make sure you are using plenty of water on the stone when you are lapping the edge. I use a spray bottle and squirt the stone every few strokes or so.
Keep your eye on that sharpied edge: When you've hit the entire bevel of the blade, work the opposite side until it's blackened edge is shiny.
When you get to the wire edge, depending on how toothy you want the final edge, switch to the next stone and gently stroke each bevel until the wire edge comes off. You'll know it when it happens.
Then you can switch over to the white stones on your sharpmaker and hit each bevel (light, even touch goes a long way) several times. Drag each bevel across your thumbnail to see if the entire wire edge has been removed.
Once you've mastered this, you will be carrying a pocket razor
