The cruciform bayonet is categorised by having the cross-section of the blade shaped as a cross. This structure makes the blade less prone for breakage compered to the sword or knife bayonet, but limits the bayonet to only being useful for stabbing. It is not suiteble from cutting or being used as knife.
Many socket bayonets got cruciform shaped blades. One example is the Swedish M/1867 socket bayonet.
