Ceramic whetstone with 2 guides.

To sharpen with a stone it is essential that the same angle is maintained between the knife blade and the stone.
The optimum sharpening angle for most cuts is between 10 and 15 degrees
To facilitate the task for the less experienced, Global has created the track/guide
The guide is in coated metal so as not to damage the blade and must be positioned on the edge of the knife, approximately halfway through the blade, as visible in the photo.
By placing the blade on the stone, the rail will allow you to maintain the optimal angle throughout the sharpening duration.
At the end it is recommended to rinse everything well to avoid the deposit of processing debris which could scratch the blade of the knife the next time it is used.
