OK Polak, you´re right as always ... I think I´ll drop the idea about repacking QuikClot.

So an other thought at this point:
Where should I apply pressure when the slashed artery (for example at the groin) is at the heart nearest pressure-point reachable ? In such a case I would try at least to close the artery in order not to drain at all - even if I would risk to lose a limb.
