REVIEW TECHNIQUES
POINT 1
FLATTEN WHETSTONE
After several uses make sure the whetstone surface is flat. Â Presoak your whetstone flattener then rub back and forth until the surface is completely flat.
NOTE: Â A whetstone flattener should be harder than the whetstone it will sharpen. Â This means the # will be a lower number grit.
POINT 2
SHARPEN IN SECTIONS
Visually divide the blade into sections. Â When you sharpen count the # of strokes per sections - they should be equal. Â Uneven sharpening will change your blade profile over time. Â Keep them the same.
POINT 3
CORRECT BLADE ANGLE
Keeping a consistent blade angle results in better sharpening.  Take your time to set up the proper blade angle, then maintain it as you move across the whetstone.  First side - position knife at 90° to the whetstone.  Raise the back of the knife until there is a 12-15 ° angle to the whetstone. Second side - position knife at 45° to the whetstone.  Raise the back of the knife until there is a 12-15 ° angle to the whetstone.
Note: Japanese knives are usually 12-15 °.  Western knives 18-20 °.  Remember - the sharper the angle the thinner the blade edge.
POINT 4
LIGHT PRESSURE + PRECISE
Use one hand to hold the angles firm. Place the finger tips at the edge of the blade where you want to sharpen. Â Use light downward pressure to keep it stable as the blade slides across the whetstone surface.
