I've use a Sharpmaker for more than 25 years. I upgraded to the latest model in the past couple of years because the Tri-Angle rods can be used at different angles now. I've got the diamond, brown and white Tri-Angle rods.
Here are a few things I've picked up over the years. I can't claim any are an original idea.
I used to use a kitchen cleanser like Ajax to clean the brown and white Tri-Angle rods, but use a pink pencil eraser, now. It seems to be faster and less messy. No pencil eraser on the diamond Tri-Angles, just water, as recommended.
On a new knife and especially on any brand other than Spyderco I'll use a Sharpie on the edge grind to figure out where the Tri-Angles are touching the edge then lean the blade more or less to remove the Sharpie ink to match the grind o' the edge. (They don't call it a "Sharpie" for nothing.)
Rubbing alcohol or acetone, (nail polish remover,) and a cotton swab will remove the left-over Sharpie ink from the blade.
When I get down to the white Tri-Angles I'll drag the flat part of my fingernail across the edge at 90 degrees to the edge, pulling my nail away from the edge. (The opposite way you'd shave something.) In doing this I can see if the edge is rolled; it's usually rolled to one side or the other. You can feel the rolled edge shaving your fingernail while the opposite side has less/no friction. Then, I'll lightly use the white Tri-Angle to "roll" the edge back straight. When I get to that point, I'm done! You can pull the blade across a dry piece of leather and get the same effect. Just like a strop.
A friend brought me a knife with a Tanto blade that had been "sharpened" by a buddy using something abrasive and powered by electricity. (If I had to guess I'd have thought it was a wood-fired grinding wheel.) His Tanto blade looked like a cross between a clip point and a khukuri blade. I placed an aluminum oxide stone on a Tri-Angle rod that was placed in the Sharpmaker base to re-profile the edge back to 20 degrees. I used the Tri-Angles to finish the job, turning it back into a sharp Tanto blade.
You can use the radiused (curved) sides of the Golden Stone to touch up the large scallops of a SpyderEdge blade; they're the same radius. Coincidence? Probably not.
