installing apt-utils themselves

[Albretch]

Hi,
.
I did a basic debian installation using knoppix and debootstrap and made the mistake to run ...:
.
apt-get -f install

So, I mistakenly removed apt-utils, apt and aptitude, which I could have kept.
.
How do I reinstalled the apt-utils themselves in order t be able to use apt-get?
.
Thanx
