Sharpal 196N Angle Pyramid.
When we talk about sharpening, we begin to deal with a complex topic and for this reason the market is oriented towards equipment such as Tormek,at sharpening stones,up to the use of the belt sanders machine, the sharpening systems Lansky,etc. I don’t even take into account the tools sold in kitchen stores to sharpen knives without having a modicum of knowledge.
This tool was born for manual sharpening on stone and goes to make you understand a fundamental element of the knife that is the sharpening angle.
Knowing the sharpening angles of a knife is essential to make the correct choices of wire angle according to the type and destination of the knife. 
As you can see from the diagram:
- Very sharp blades sharpen to 10 – 15 degrees.
- Normal blades sharpen to 20 – 25 degrees.
- Knives that need a hard edge (such as those to cut) sharpen to 30 – 35 degrees.
- For an extremely long-lasting cut the blades are sharpened beyond 30 degrees.
This tools is useful for sharpening knives with sharpening stone and angle guide, it is sold in a 2-piece package with 4 universal angles (14°, 17°, 20°, 25°)
The orange corner guide is equipped with a magnetic base applied to sharpen the ferrous metal stone while the black one is with non-slip rubber base applied to traditional sharpening, ceramic stone etc.
3) Apply a continuous, circular or alternating movement to the blade on the stone, being careful to keep the sharpening angle constant and to keep the blade always in contact with the surface of the stone. To calculate the exact inclination of the blade, based on the following table: measure the width l of the blade, and get from the table the height at which you need to place the blade on the thumb. Important!! Always count alternating rotations or movements and repeat the same number from both sides. The number of movements varies depending on the hardness of the blade steel, it takes at least 50, up to 100 for the hardest steels. 
So the real key to a nice sharpening of the knife is a suitable and constant angle on the bevel of the blade.
Conclusions
Learning to sharpen requires a lot of practice, really a lot and this tool can be useful to have a correct start of the sharpening angle and continue freehand.
Do not expect to get great results right away but try, try again and if you follow all the instructions calmly and precisely you will get a good sharpening.
In the house people always have knives that they do not use because they no longer cut ask people to let them give and sharpen them, exercise.
With time and experience, you will be able to get a blade with an incredible cutting ability! Make a good sharpening!
