KAI knife sharpener AP-0308 used both diamond and ceramics as abrasive.This makes it perfect when sharpening hard types of steel.
With this KAI sharpener you can sharpen knives with a two-sided grind in three phases. From blunt to razor-sharp in no-time!
Each of the three sharpening slots uses a different sharpening method. The first slot contains two small diamond sharpening stones with grain size 270. Relatively coarse and therefore perfect for the first sharpening phase to restore a blunt edge.
Step two is the ceramic sharpening wheel with grain 150. A coarser grain than the diamond stones, but with a less aggressive function. Finally you use two ceramic sharpening steels for step three. These have a grain size of 1000 and are, as a result, perfect when polishing the edge
