how to sharpen scissors,
Sharpen the cutting blade by firmly gripping the handle and holding the whetstone in your dominant hand, aligning the concave part of the whetstone vertically with the angle of the blade. It is better to sharpen the knife while holding it firmly without opening it.
Sharpen the receiving blade if the cutting edge is chipped or worn. To sharpen, place the convex part against the receiving part in the open state, and apply it perpendicularly to the blade. If you want to sharpen completely, it is best to sharpen in pieces.
If the blade is chipped, use a rough whetstone to repair the chip and sharpen it using a medium whetstone in the order of sharpness. If you only want to restore the sharpness, please sharpen with a medium whetstone.
*Caution: Please avoid sharpening the back of the cutting blade and receiving blade as much as possible. Scissors are tools that cut by meshing two blades. If the blade opens up when sharpened, there is a risk that it will not fit together at all and become unable to cut. We recommend only removing burrs after sharpening the blade surface. If you are storing it for a long time after finishing, don't forget to wipe it with oil such as camellia oil.
