It is more important to keep the blade sharp, than whether your knives are inexpensive or very costly, so you need a high quality sharpening stone and proper instruction.

Before use, you should read our instructions to produce the sharpest blade:
Step 1: soak the sharpening stone in water for 5-10 minutes, place it on a sturdy flat surface. (drop water on the sharpening stone surface while sharpening, although the it has been soaked)
Step2: 3000 grit side for sharpening:
A: Dominate hand is to maintain the proper angle of the blade, the opposite hand use 3 or 4 fingers to apply pressure, have the back of the blade lead the knife across the entire whetstone surface.
B: works with one side at a time, once you feel a slight burr on the opposite side of the edge, then change side until you feel slight burr too, using short upward motion remove the burrs.
C: when looking directly at the blade, you should see blade line.
Step3:8000 grit is for honing, repeat the same way as above.
*The cutting of knife tends to fold over with use, which make it dull, so honing is used, honing straightens the cutting edge of knife, and keeps knife working well before it is necessary to grind away material and re-profile the blade of cutting knife.
*as you sharpening on 3000 grit side, there will be small scratches and still burr ,so you can smoothing out scratches and remove burr with 8000 grit side, create a more polished, sharper edge.
