Maestro Wu Artillery Steel Chinese Chef's Knife


Maestro Wu hand forges knives from salvaged artillery shells fired on Taiwan by mainland China since the early 1900s. Artillery steel makes a strong blade not prone to rusting or chipping. These classic Chinese knives and cleavers are renowned across the world by the Taiwanese diaspora for quality and craftsmanship. View our full Maestro Wu collection here.

The Maestro Wu Chinese Chef's Knife is designed for slicing vegetables and chopping meats, and is incredibly versatile. Though similar in use case to the classic Chinese Vegetable Cleaver (菜刀), this knife provides a pronounced rocking motion and has a pointed tip. If you're more familiar with the chef's knife style, this might be the knife for you.

For chopping through bones, we recommend you use the Maestro Wu Meat Cleaver. The two together pair very well, and we sell them as a set.

Maestro Wu Knives has been operating on Kinmen island since the 1930s. They experienced material shortages during the Second World War and begin to collect spent artillery shells as a source of steel. Their knives are still made from shells; millions were fired on Kinmen island by China during the Second Taiwan Strait Crisis in 1958.

Wanting to give this as a gift? It’s bad luck in Taiwan to gift knives for fear of cleaving the relationship. But don’t let that stop you from getting this perfect knife to your loved one. We suggest asking the recipient for pocket change or a small object as a trade—skip the bad mojo.
