Ji Xiao Xin Shu

The book Ji Xiao Xin Shu (紀效新書, aka. Chi-hsiao hsin-shu) was written by the Chinese general Qi Jiguang (戚继光) of the Ming Dynasty. The title can be translated as New Book Recording Effective Techniques.

In the book Qi Jiguang writes about strategy, armed and unarmed fighting and many other aspects of warfare. It also set certain standards for the forging of weapons, this is what he wrote about the forging of the short sword:

“

The following steps in the manufacturing process of the short sword are necessary:

  1. The material of iron used must be forged many times (that is heated, hammered and folded numerous times).
  2. The cutting edge must be made from the best steel, free of impurities.
  3. The entire part of the blade where the back or ridge of the blade joins the cutting edge must be filed so that they appear seamlessly joined together. This process is necessary to enable the sword to cut well.
 ”

It was also general Qi who promoted the training of unarmed techniques (quan fa). He didn't see much use in it on the battle field, but thought it provided a good basic training for his soldiers.
