If it cuts we use: A rifle
The rifle allows to maintain the thread so it is used when the knife still cuts. The method is as follows: you need to take a quality rifle that is magnetized, making about 25 cm of wick. You must place the knife on top of the wick forming an angle of 30°, then while pressing well on the blade, go down your knife along the wick while continuing to maintain 30° of angle without scratching it.
This operation takes only a few minutes, we advise you to start with an old knife to find the right gesture.
Please note that sharpening with fast movements does not bring anything to the quality of the sharpening and you risk scratching your blade.
