Step 1 - select the proper side of the stone
Step 2 - set a stone on a stable flat surface
Step 3 - apply few drops of Nathan´s Honing Oil(opptional but recommended)
Step 4 - observe the bevel angle you intend to sharpen; bring the edge to the stone matching your sharpening angle and push the edge off the blade across the stone in one motion (like trying to slice a thin layer of the top of the stone); maintaining a consistent angle for best results.
Step 5 - repeat 3 - 4 times then switch to other side and repeat
Step 6 - repeat until the edge is sharp
Step 7 - clean stone after each use and store in cool dry place
Note: Read the instructions before use. Do not rush and pay attention to what you do. Knife sharpening is an inherently dangerous activity - if you use this sharpener properly you can not be hurt but a careless handling can hurt you.
