Extrema Ratio LKU01 Luce is a new, limited-edition version (only 100 pieces) of the popular LKU01 EDC knife. The blade features a satin finish and is made of Böhler M390 steel. The handle scales are crafted from carbon fiber, a material known for its high mechanical strength and vibration-absorbing properties, making the grip more comfortable to use. The Extrema Ratio LKU01 Luce weighs 109 g. Its stainless steel pocket clip is removable and ambidextrous. The clip is shaped like a horseshoe, paying tribute to Italian fighters of the 1800s and 1900s who used this symbol. The LKU01 Luce comes in an elegant black box that includes a carbon fiber card signed by master bladesmith Danilo Rossi Lajolo di Cossano. The card has rounded corners, but its lower edge is sharpened, allowing it to be used for defensive purposes if necessary. You are advised to check your local laws to ensure that the use, carrying, and transportation of this tool are permitted in your country.

Extrema Ratio knives are a part of equipment of many special military units of Italy, the police and rescue services. Each model is developed very carefully and undergoes a series of rigorous tests before it is put into production. Extrema Ratio cooperates with the University of Perugia, where scientists conduct a number of studies determining the ergonomics of Extrema Ratio products and methods for improving it. The office of Extrema Ratio is located in Prato, Italy. Both Extreme Ratio tactical knives and EDC knives are distinguished by impeccable quality. Most knives are made of Austrian steel N690, which is famous for its high content of molybdenum and cobalt and is highly corrosion resistant. Due to this, N690 steel has increased strength and resists shock loads well. The most popular Extrema Ratio knives are Fulcrum, Col Moschin, RAO, Adra and others. Extrema Ratio also produces several lines of tactical folding knives: BF (basic folder), MF (medium folder), BD4, BD2 series and other knives. In our store you can buy Extrema Ratio tactical knives, as well as folding and EDC knives of this brand. MyGoodKnife is the official distributor of Extrema Ratio.
