Guide to sharpen

Useful guide for Super Togeru sharpening, perfect for sharpening the blades of your western style knives on stones giving the right cutting angle. The use of a sharpening guide serves to keep the angle between the blade and the stone constant when sliding the first over the surface of the second: an angle of 15 ° is the recommended one to sharpen the entire surface of the line evenly.
The guide must be inserted on the upper edge of the blade, after which it allows the latter to slide on the stone in the correct way.
