Depending on the condition of the blade, is made Carbide Ceramic + (Serrated Ceramic for "teeth" on the bi-blades)
or Ceramic. The stem is used only to catch up with dull blades / very damaged.
Dull blade: diamond pin followed by + Carbide Ceramic
Blade lawless wire: Carbide and Ceramic
Blade maintain sharp, straight wire: Ceramic only
(1 with two passes per stage)
The angles of the tool are positioned at 22.5 degrees. So you have to hold the tool with one hand, and the knife must be placed at 45 degrees, and it must pass the blade without pressing too hard 1-2 times, no more, and always in the same direction (in the direction contrary to the blade cutting direction). You sharpen the blade by asking, you do "back" or "bump" in his _sens_opposé_à cutting. Remember to move your blade under water before the drag on the course tool (or even better if you have: (1) Japanese Katana oil (2) Break-Free).
You really have to be careful not to press hard: we slide with light / medium pressure any more, just the same pressure as a razor pass over the skin. One or two passes moderate pressure and then tested on an apple, and if it's good, 1/2 lighter passages to narrow.
The tool "Carbide" is one that will wear out as quickly: so it should be used moderately, and only if the blade wire is not perfectly straight (you can "feel" by Drag in the opposite direction of cutting blade on its index).
The diamond pin can be used to refine / maintaining a blade that is sharpened already, but for that I would rather recommend to spend the blade on a strip of leather: the radius "razors / shaving accessories" you can find tool made from leather to sharpen the cutting cabbage: a blade to narrow it best: + dry blade passages in the opposite direction of the cut sides of the blade).
This tool has a metal body, which really sets over plastic ones: not only for its strength over time, but also for its safety. The tool is a bit heavier, but also longer. The rod impregnated with diamond powder can be oriented 180 degrees, and a fairly strong magnet keeps it pressed against the tool when it is not used: no danger of this leading to walk in the bag ...
The tool is very well designed: a rod to catch up very damaged blades and a sharpening in two stages with the teeth to straighten Carbide, Ceramic to refine. The "Cerrated Ceramic" is intended to sharpen the hollow teeth on the twice-blades consist of a blade edge end, and "hollow" to the base of the blade (these knives are provided for cutting the skin from animals to hunting, then stuck his leather in a hollow, and this opens the belly of the animal to remove the viscera without the blade does not move relative to the leather skin).
