Devious Dagger was obtained by redeeming its now expired code, added on June 28, 2020. It is an all white knife complete with a black hilt and handle, representing Dr. Devious' main colors. Of course, it is one of the two matching knives for Dr. Devious, the other one being Dr. Devious' Roses. This knife looks similar to Motif Dange, the only difference being the hilt and handle's colors. It has normal sound effects and range if equipped when playing as the killer. This knife doesn't have very much demand as of now, but it holds OK trade value due to being an expired code.
