I bought the sharpmaker last week and over this past rainy weekend started to practice/use with it. From my infinite wisdom, I decided to start with my utility knife, an SP-25 survival knife. It took a long, long time and over 20 times 20 passes on diamond, medium and fine stones to get it sharp enough to shave hair of my skin. I will not do that again.
After reading most of the threads here regarding the sharpmaker, I decided to check the actual sharpening angles of each rod on each slot. I found out that on the 40 degree slots, the diamond rods average from 21 to 22 degrees, the medium rods were between 20 and 21 and the fine rods were 19 to 20 degrees.
I know one degree is probably not much for many other things, but after seeing the burr (light at the end of the tunnel) using the diamond rods, the knife did not pass the sharpie test when I switched to the medium rods.
Is all this sound normal to you guys/gals? Another thing, the diamond rods are "softer", I meant, not as abrasive, than when first used.
How do if the diamond rods are still good?
Thank you much for your help.
