OS3 Multifunctional 5 in 1 Knife Sharpener Black for knives, for everyday use at home, in the workshop, in the field, etc. Perfect for the kitchen as well as for an outdoor trip, camping, etc. where there is a need to ensure sufficient sharpness of our working knives.
The sharpener is equipped with: 2 sharpening slots (tungsten and ceramic), an oblong ceramic stone with a groove, a tapered diamond rod and a bottle opener. Each of the elements has its purpose. The 
tungsten carbide V-Slot will rebuild a damaged blade and the 
ceramic V-Slot will ensure quick sharpening and polishing of the cutting edge. The 
ceramic stone will sharpen any type of knife and the 
two-sided groove designed in it will restore the sharpness of fishing hooks. The 
tapered diamond rod will carry out the sharpening process of serrated, curved, smooth, hook blades, etc. The 
bottle opener, so often used by practically all of us, is just a nice addition to a functional whole.
