Something about our knife
Every product of COZILIFE is living up to our company moto, providing the best quality with a modest offer.
We don't want to talk about the obvious, the product stands for its fine craftsmanship all by itself. We want to tell you what is behind the scene. The steel of this knife is German made, formula X50CrMoV15 in particular. The steel is commonly used by major German knife manufacturers. But with our unique forging process (increase the density and the carbon content of the blade) and triple-heat-treatment technique, we achieve the hardness of 57°±1° HRC rather than 55° for most of the German knives. As a result, the knife's sharpness retention is much better which means you don't have to grind it frequently and also it is not too hard that you can't grind it at all.
We are devoted to making your house a home and hope you will enjoy this fine cutlery of ours.
COZILIFE recommends washing all knives by hand. For best results, hand wash the knife with a soapy cloth and dry immediately.
We recommend hand washing as dishwashers are designed to spray water at a relatively high pressure, which can jostle the silverware and cause the knives to collide, dulling the edge.
Sharp Knives are Better for Food
When cutting a tomato, have you ever smashed it? Have you cried when cutting an onion? These problems are caused not by the food but by a blunt knife. A blunt knife adds extra force to the cut surface, and the food cells collapse. For food, such as an onion, the lachrymator within the cells is released as the cell collapses, causing the tears in your eyes to flow. In addition, when cutting thin, soft food like fish or a tomato with a blunt knife, you have to move the blade back and forth for many times. When this happens, the color at the cut surface becomes dull, the luster appearance was gone, degrading the fresh look of the food. Moreover, oxidization develops rapidly at the cut surface, so the food loses firmness and taste. In other words, the sharpness of a knife is a decisively important issue for cooking.
Sharp Knives are Better for You
A sharp blade is predictable. When it strikes or is drawn across the food's surface, it won't slip. This makes it easy to control how the blade moves through the food, giving you control over your chopping or slicing. A dull blade will slip, which makes control difficult and increases the risk that it will slip into your finger. With a dull knife, it's only a matter of time until you badly cut yourself.
Knives Need to Sharpen More Often than You Think and Learning to Sharpen is an Investment
Perfessional chefs sharpen their knives on daily basis, and during cooking they will do a quick sharpening with a honing stick in every 5 to 20 minutes depending on which food they are processing.
A set of waterstones for sharpening your knives will cost about as much as a good knife. We think this is a great investment since a whole set of expensive but dull knives is useless. A couple rounds at a sharpening service will cost more then a set of stones, and the stones should last you a lifetime.
The Forged Blade
Forged blades are made in an intricate, multi-step process, often by skilled manual labor. A chunk of solid or powdered steel alloy is heated to a high temperature, and pounded while hot to form it. The blade is then heated above critical temperature (which varies between alloys), quenched in an appropriate quenchant, and tempered to the desired hardness. After forging and heat-treating, the blade is polished and sharpened. Forged blades are typically thicker and heavier than stamped blades, which is sometimes advantageous. (wikipedia)
Mirror Polished Finish
A mirror polished finish is done by hand, polishing the metal into a highly reflective surface. While it provides a great look and offers better corrosion resistance due to the smoothness of the blade, this finish type involves a lot of polishing to maintain its look and its reflective quality would be telling in tactical fieldwork. The amount of skill used to create this finish often results in an expensive blade.
