This sharpening system is the first in the world to completely eliminate the effect of the raised bevel at the tip of the knife and allows for absolutely precise repeated sharpening of the knife without any demands on repeating the knife clamping position. The KMFS Vantaedge sharpening system for absolutely precise maintenance of the knife sharpening angle - repeatedly. No matter how you hold the knife, you will always sharpen the bevel at the precisely selected angle. The ingenious patented arm with the help of reverse kinematics always ensures a precisely set angle. And it does not matter if you clamp the knife inaccurately or at an angle. The selected angle options are: (on the basic head you can choose from 15°, 17.5°, 20° and 22.5° angles or 30°, 35°, 40° and 45° of the top total bevel angle. An adjustable head with gradual stepping of precisely adjustable angles in the range of 10° to 29° on one side is also available - it is not part of the delivery and will be available separately as a possible accessory. Precisely adjustable angle regardless of the thickness of the knife or the height of the grinding plates. You will always hit the precisely set angle, and then just drag the blade with a finer sharpener is enough. The advantage is that you do not remove unnecessary material on the blade. You simply hold the sharpener in your hand or put it on the mandrel. The set angle is from the beginning of the blade to the tip, regardless of how many times and how you clamp the knife. You can always rely on VantaEdge. Even if you clamp the knife crookedly, or every time differently, you will always achieve the same grinding angle on both sides. The centered and very strong and stable clamping of the knife is ensured by the help of cup nuts that do not let go of the knife. Simple and patented solution from KMFS. Developed and manufactured in the Czech Republic. As for maintenance, use a dry or oiled cloth for cleaning, certainly not water. Linear bearings - there are three in the device, two on the arm and one on the clamp. A drop of the included FP10 oil is enough for them, about a drop once every 5 hours of use. Sharpener - the main parts are made of duralumin 7075, the stand plate is made of 6082 material. The guide rods are made of surface-hardened stainless steel rods, again of the highest quality. The integral KMFS Vantaedge clamp is symmetrical and by simply turning it, it is possible to sharpen the other side of the knife without having to rotate the knife in the clamp. The set is completely equipped with ball bearings for absolutely smooth operation without play. There are 4 pieces of completely covered bearings for rotation around two angular axes and 3 pieces of double linear four-row bearings. The set has a sharpening stone holder that is able to clamp all KMFS Rival stones and most stones from other manufacturers, where there is no problem with the transition of the abrasive, there is no need to adjust the set in any way for a different thickness of the abrasive, the kinematics always achieve the correct angle. The stone clamping segment held by a stainless steel spring has integrated brass pins that protect the hand from contact with the knife blade during sharpening. The segment control wings also allow precise guidance of the sharpening stone. https://www.kapesni-noze.cz/brusky-na...
