Is it possible to cherry-pick a commit from another git repository?

Question

I'm working with a git repository that needs a commit from another git repository that knows nothing of the first.

Typically I would cherry-pick using the HEAD@{x} in the reflog, but because this .git knows nothing of this reflog entry (different physical directory), how can I cherry-pick this, or can I?

I'm using git-svn. My first branch is using git-svn of the trunk of a Subversion repo, and the next branch is using git-svn on a Subversion branch.

The answer, as given, is to use format-patch but since the question was how to cherry-pick from another folder, here is a piece of code to do just that:

$ git --git-dir=../<some_other_repo>/.git 
format-patch -k -1 --stdout <commit SHA> | 
git am -3 -k
