Sharpening

once you have created the burr you begin the sharpening process
start at one end of the blade with the stone in the lowest position
move in a forward and upward motion along the length of the blade
alternate both paddles like you see in the demo video
as you gain experience you will become faster at this
if you find yourself bumping the paddles together on the reverse stroke, try arcing one side away from the blade, this should solve this problem

do not go over the edge of the knife if you go from back to front, just go to the edge of the knife
do 20-25 strokes with each stone
move progressively through all the stones up to your highest stone (1000 or 1600, or higher if you have Water Stones)
again - for the sake of safety, hold the paddles as low as possible. This keeps my fingers away from the edge of the knife
