There are many tutorials that the sword -to -sword printing knife cannot be released, but I measure many printed knives in the MC1.7 version to release SA.A bit partial, I haven't tested it, and I hope that the big guy adds it.

Summarize the laws here

Except for puppets, white sheaths, bamboo light, silver paper and bamboo light, etc., other knives cannot follow this law.

The SA of the Printing Knife and its rename became the SA when they became a demon sword.

The printed knife can also be changed to SA with SA Orb, and after being renamed as a demon knife, it still maintains the SA before the rename. After the demon knife is changed back to the printing knife, SA remains unchanged.

In the end, because I have insufficient ability, I hope that there are big guys to add to add and give novice more correct guidelines (how difficult the days when I was exploring.)
