-Lansky LKDMD is a professional sharpening system, consisting of 4 diamond stones of different gradations, a clamp and guides, allowing you to choose the right angle and maintain full control over the sharpening process. Lansky sharpening systems are widely recognized as one of the best and relatively cheapest professional sharpeners in the world. Based on many years of experience, Lansky has created an extremely simple and efficient system that allows you to choose the sharpening angle depending on the type and purpose of the knife, and to perform grinding very precisely while maintaining a constant angle. Contrary to the classic "hand sharpening" that requires skill and experience, the system allows you to maintain the proper angle control, thanks to which we can be sure that the sharpening will be carried out correctly. The effect of such sharpening is easy to predict, the cutting edge is perfectly sharp and retains its working sharpness much longer. The set with diamond plates is designed for sharpening knives made of hard, highly hardened steel, eg CPM-S30V or M390. The ease of use, great efficiency and effectiveness of Lansa systems mean that our knives can always be "razor sharp" without having to purchase several different sharpeners. Construction and operation The system consists of a clamp, metal guides and grinding stones. The T-shaped aluminum clamp is used to firmly fix the knife, preventing it from moving during grinding. After embedding the knife in the clamp jaws (using screws), connect the guide with the grinding stone, then select the angle that best suits the type and purpose of the knife. Adjustment of the sharpening angle is made in a simple way - by placing the guide in the cutouts with predefined angles: 17 °, 20 °, 25 ° and 30 ° . The clamp has a double-sided construction, so to sharpen the other side of the blade, you just need to turn the clamp and move the guide with the stone, without having to disassemble the knife. Sharpening angles The clamp has 4 sharpening angles designed for various types of knives: 17 ° - filleting knives, kitchen knives, precision cutting tools, 20 ° - kitchen knives, pocket knives, small edc folders, 25 ° - large EDC folders, hunting and outdoor knives, 30 ° - survival knives, tools for hard work Stones The Lansky LKDMD set includes 4 diamond stones , enabling the main activities related to the repair, sharpening and smoothing of the cutting edge. Steel plates with an evenly raised diamond coating were mounted in polymer housings with a different color, allowing for quick identification of each gradation. The diamond coating is harder than the sintered carbide, thanks to which the sharpening process is quite easy and fast, and it does not require water and oil. In order to maximize the service life of the diamond plates, do not press down hard on the blade when sharpening. Pre-clean the diamond tiles with a nylon brush (included), then wash them in warm water with a mild detergent. Stones included : Lansky Extra Coarse Diamond LDHXC graded 70 is used to repair and reprofile the cutting edge. Lansky Coarse Diamond LDHCR with 120 grit is used for pre-sharpening and repairing damaged cutting edge Lansky Medium Diamond LDHMD with 280 grit is used to give the working sharpness and sharpen very dull cutting edges Lansky Fine Diamond LDHFN with a gradation of 600 fine is used to smooth the blade and quickly sharpen slightly dull edges. If we want to increase the stability and comfort of sharpening, it is also worth considering the purchase of the LM010 vice, used to attach the system to a table or table top. The set includes a nylon cleaning brush. Carrying the elements of the Lansky LKDMD set is facilitated by a closed polymer box.
