Included angle adapter swaps out for use with European or Japanese blades2 sets of sharpening stones with different grains/grits included – Course and Fine Never a dull knife again! Its time to sharpen like the professionals. Included in this set is a ZWILLING Pro 7″ Chef Knife and ZWILLIN V Edge Sharpener. Anyone whose ever prepared food with a truly sharp knife knows the incredible experience of using one. However, even the best blades lose their edge over time. Regular sharpening is crucial for maintaining their quality over the long term. But before you reach for a whetstone or sharpening steel and spend hours online looking for instructions on how to sharpen a knife correctly, take a moment to read on. Its patented sharpening mechanism is incredibly simple and wholly effective. Simply pull the knifes blade at a diagonal from above in a downward direction and the V-Edge does the rest. The V-shape arranged ceramic sharpening stones evenly sharpen the entire length of the blade without risk of damaging it. Different angle adapters are included for European (like the ZWILLING PRO Chef Knife) and Japanese knives. A lot of work has also been put into the exceptional design and premium workmanship of the V-Edge to make sure you see at first glance just how good it is. Instead of hiding it away in the cupboard, simply place it on the kitchen counter and leave the fine grain sharpening stones installed. That way, you can simply pull your knives through the V-Edge a couple of times before each use. Your knives will retain their professional sharpness and youll enjoy cooking with them even more.
