The Dagger of Deng Wa is a legendary weapon that was very briefly mentioned by Po in Secrets of the Masters. The dagger's origins and uses are currently unknown.
Description
Though unconfirmed, the dagger may possibly share some resemblance to a trowel, seeing how Po mistook the trowel Shifu handed him in Secrets of the Masters for it.
History
In Secrets of the Masters
There is nothing else known about the dagger other than its brief mentioning by Po in Secrets of the Masters. After having broken into the new Masters' Council exhibit by making a hole in the roof, Po was ordered by Shifu to repair it and handed him a trowel. Po at first thought it looked like another legendary weapon and tried making a few guesses to what it could be. The Dagger of Deng Wa was one.
