Kakui Zebra Planer for Plane and Whetstones (Main Unit)

Before use, peel off the backing paper from the blue paper if you are straightening a whetstone, or the red paper if you are straightening a plane base, and stick it on the glass (5mm thick) of the main body. Features: As you use a whetstone, the center will gradually wear down and become concave, but you won't be able to get a good edge unless the sharpening surface is flat, so once there is a certain amount of misalignment, you must straighten it to make it flat. This is a surprisingly tricky job, but using this Zebra straightener makes it incredibly easy. Method 1 for straightening a plane base: With red sandpaper still attached, retract the plane blade slightly (2-3 mm) (it's best not to remove the blade). Method 2 for straightening a plane base: Place the bottom edge (the surface to be sharpened) on the base and grind back and forth in a straight line to make it flat. Method 1 for straightening a whetstone: Remove the whetstone from the water the day before and use it when it's dry. Method 2 for straightening a whetstone: Place the surface to be sharpened on the base with blue sandpaper still attached and lightly grind back and forth to make it flat in an instant.
