How to quench a kitchen knife to make it tougher and sharper?

There are many kinds of quenching methods for kitchen knives, and different steels use different quenching methods. I told you that many blacksmiths in ancient times were proficient in quenching. Their swords are also very sharp. As for today's tool masters, few can really master quenching. In my hometown, there are generations of traditional blacksmiths whose tools are not only sharp, but also very tough. If you are interested, you can go to Tangcun Town, Jiahe County, Hunan Province to search and learn about the local traditional crafts. You can also search Taobao (Chenzhou specialty kitchen knife) or (Jiahe Tangcun kitchen knife) to find out!
