Blade filing

Once you have finished the preliminary stages, the following step is to smooth the tooth of the blades one by one until they are smooth. Make a start at the lower front corner of the blade’s very first tooth with the diamond file and move its file forward as well as upward evenly along its edge as much as possible. The face of its file must be on its flatter side of the metal’s thickness when it is being used. Run the blade smoothly over its top flat area of a tooth, using a similar pattern as before. When you’re doing this, you shouldn’t put your finger on the point.

Repeat the 2nd step

Continue the filing on all of your teeth till you reach the tooth that was originally indicated. When sharpening its teeth, one should avoid making contact with the tips or edges of the tooth. As soon as you are finished with 1 side of its blade, flip it over and sharpen the second half by repositioning the blade over its clamps in the same manner as you performed with the 1st side. By the time you reach the teeth with the marking, you have finished the sharpening steps throughout the whole blade.
