Split large Git repository into many smaller ones

After successfully converting an SVN repository to Git, I now have a very large Git repository that I want to break down into multiple smaller repositories and maintain history.

So, can someone help with breaking up a repo that might look like this:

MyHugeRepo/
   .git/
   DIR_A/
   DIR_B/
   DIR_1/
   DIR_2/

Into two repositories that look like this:

MyABRepo/
   .git
   DIR_A/
   DIR_B/

My12Repo/
   .git
   DIR_1/
   DIR_2/

I've tried following directions in this previous question but it doesn't really fit when trying to put multiple directories into a separate repo (Detach (move) subdirectory into separate Git repository).

git split repository git-filter-branch

Thanks for your answers but I ended up just copying the repository twice then deleting the files I didn't want from each. I am going to use the filter-branch at a later date to strip out all the commits for the deleted files since they are already version controlled elsewhere.

cp -R MyHugeRepo MyABRepo
cp -R MyHugeRepo My12Repo

cd MyABRepo/
rm -Rf DIR_1/ DIR_2/
git add -A
git commit -a

This worked for what I needed.

EDIT: Of course, the same thing was done in the My12Repo against the A and B directory. This gave me two repos with identical history up to the point I deleted the unwanted directories.
