This is one of the best knife you can use as a chef. I saw this kind of knife the first time in Serbia (ex Jugoslavia) and i was impressed, but I couldn't buy one that time.
Then I saw many food videos of Almazan Kitchen (Youtube) which they exclusively us such knifes and i ordered one, but never received it.
Few months ago I discovered, that you sell such kind of knifes, so that i immediately ordered one. I use it daily in our restaurant kitchen and few weeks ago, I ordered an other 2 pieces...
