I find it interesting how dean always flips the blade up - ideal for attacking with an upwards blow, or from below. Cas, however, flips the blade down, ideal for attacking from above or with an overhanded blow. Different fighting styles for different lives; Dean clawing his way up from the bottom, Cas falling from on high.
