 SCP-034 is a primitive knife constructed out of pure obsidian. Tests reveal that SCP-034 is approximately 1,000 years old. Despite its crude method of construction in age, SCP-034 is still incredibly sharp and requires no maintenance to retain its edge. Expert analysis hypothesizes that SCP-034 may be of South American origin. SCP-034 is the ability to allow its bearer to take on the appearance of another individual. If SCP-034 is used to cut a piece of flesh from a living individual, and that piece of flesh is placed against the skin of another individual, the second individual would take on not only the appearance, but all physical characteristics of the first individual.
