- Weight: 4 grams (10 grams with Double Bearing Core)
This Blade Base can only house the Double Bearing Core. Only the shaft of Burning Kerberous and the shaft of Wolborg 2 can fit into the Double Bearing Core. Therefore, there are only two ways the BB can be used. The blade base can be used with the Burning Kerberous shaft inside the bearing cases, which has great endurance, or it can be used with the Wolborg 2 shaft, which stays fixed when placed in the BB. The Wolborg 2 shaft, when fixed in place, is used for attack combinations.
