User blog comment:Soulreaper1234/What's up with Ichigo and his BANKAI, is it in constant release?/@comment-1393830-20100915044931

A constant release type is merely a Zanpakuto that because of its owners constantly leaking spiritual pressure, is always in its released state. It is in no way superior to a regular Zanpakuto. If Kenpachi or Ichigo were able to finely control their spiritual pressures, they would be able to reseal their swords. There is no such thing as a constant release Bankai. Ichigo is able to maintain his Bankai for long periods of time due to how all the power of it is compressed. It does not take the mass amounts of power that other Bankais take
