As the title says, Hidden Cut won't grant you the Blood Taken status even if the weapon used for it is enchanted with it, despite it doing physical damage and the description stating it's physical damage in general.

I'm main-handing a Bloodtaking Hisen if it's relevant, the hidden cut effect is its potential.

Bloodtaking only triggers for damage instances that trigger on attacked effects. Hidden Cut is status damage and does do not do this (neither does field or bonus damage).
