Double Ace woodworking axes have anti-counterfeiting marks that are different between genuine and fake ones.

There are two kinds of double kings, Haicheng and Anshan. The good thing about Haicheng is that the trademark was registered by him. This is a practical woodworking ax and double king ax.

The "Double King" brand ax was born in the 1950s. At that time, "Double Ace" Ax was a noble member of the Ax Gang. An ax consists of two parts, a metal ax head and an ax handle. There is also an ax blade on the ax head. The ax head part is made by forging process, and the ax blade part adopts steel lamination process, with one side made of hard steel and the other side made of soft iron. It is easier to sharpen the ax blade in this way, and the resulting edge will be sharper, tougher, and less likely to chip. The ax handle is made of mahogany inlaid with copper. Now the mahogany body has a beautiful patina. It can be said to be a very good-looking right-edged axe.
