SCP-034 - “Obsidian Ritual Knife”

SCP-034, AKA the "Obsidian Ritual Knife" is a class and item SCP which appears as a short knife with no handle. It is made entirely out of obsidian. It is approximately 1000 years old.
===Anomalous abilities===
SCP-034 can disguise the user as whomever they kill. When SCP-034 is used to impale another individual, anomalous phenomena occurs. Firstly, the impalement is lethal to the victim, regardless of what was impaled. Secondly, the victim’s attire and inventory is transferred to the user of SCP-034. Additionally, the name tag and rank tag is also mimicked to the former victim. The only parts that don’t transfer are the usernames and the ID, allowing individuals to steal identities.
==Containment==
SCP-034 is contained within the Clean Rooms in a small wooden box. The box is stored with the rest of the small items SCPs in the CR storage area. SCP-034 can be used in any providence and moved to other sites for research purposes. SCP-034 is a very low-risk SCP and so requires no further containment procedures.
*Spectators must be SC-1+.
==Testing==
To test on SCP-034, you require the ScD rank of "Junior Researcher" and a CR escort. SCP-034 is a very good SCP for cross-tests, so many tests are based on it. 
All Test-Subjects should be terminated if they have SCP-034 and can not get rid of it. Be wary that Class-Ds may use SCP-034 mid-test and escape.
