We know very little about the evidence after the arrest since everything has been under seal, but law enforcement did say early in the investigation, but after the report from the medical examiner/coroner, they believed this was the type of weapon used.Respectfully, we don't know if the sheath actually housed the actual murder weapon either. For that matter we don't even know if it really was a kbar knife that was used in the crime either.

Amid the ongoing investigation into the death of four University of Idaho students, there have been reports of police searching for a specific knife that could have been used.
"There has been much conversation about the terminology used to describe the weapon," the Moscow Police Department said in an update on Tuesday night. "The type of knife though to be used in the attacks is believed to be a fixed-blade knife. Detectives continue to look for the weapon."
The update comes just a few days after the Idaho Statesman reported that the manager of the Moscow Building Supply store said investigators visited his location several times asking if anyone had recently purchased a Ka-Bar brand knife.
