Peter
No roman soldier actually had his ear cut off. The incident occurred as soldiers came to arrest Jesus, and with them were some officials from the chief priests and Pharisees. The gospels of Matthew and Luke do not record the name of the disciple who cut off the ear of a servant of the high priest. John 18:10 records that it was Simon Peter, and that the servant's name was Malchus.
When Jesus was on the cross no knife was used by the roman soldier , he used his spear.
That was Peter, who cut off Malchus' ear.(John 18:10)
if you're referring to when Jesus was arrested, then none. after peter cut off the ear of the servant, they all fled.
Luke 22:47-51
When Jesus was being taken away by the soldiers, his most beloved disciple, Peter, cut off the ear of one of the soldiers' slaves in an attempt to protect his Lord. Jesus rebuked him, touched the year of the slave, and restored it to it's place.
John 18:10 - Then Simon Peter, having a sword, drew it and struck the high priest's servant, and cut off his right ear. The servant's name was Malchus. [NKJV]
Peter did not do anything to one of the Roman soldiers who arrested Jesus as the Roman soldiers were not involved in the arrest. The High Priest sent some persons along with some Temple guards to arrest Jesus. One of these persons was "Malchus" who was a servant of the High Priest. Peter drew his sword and cut an ear of Malchus off. Jesus took the ear and placed it back on Malchus' head. This is the only place in Scripture where Jesus healed a fresh wound.
