Dazu Longshui's "Dengjia Knife" is an independent trademark. When you go to the hardware market to buy it, you should pay attention. Either the knife maker's surname is Deng or the Dengjia Knife. The Dengjia Knife is passed down from ancestors. Today, it is famous for its forged knives. As far as I know, their manufacturer has opened two direct online malls, Tmall and JD.com. If you are far away from Dazu Longshui, you can go to their online mall to buy. If you are close to Longshui, you can go to the wholesale department of the hardware market to buy it, or you can buy it directly from the factory. Hope this answer is adopted. .
