What are some things to replace cutting?

I used to cut. It’s been quite some time (at least 3 years) since I’ve done it. And I have to say I’m proud of myself for having the self-control to stop. It’s not easy. And, lately, I’ve been feeling to urge to do it again when I’m upset (I’ve resisted).

I’m wondering if anyone has found any good replacement form of release. For example, some smokers will hold a pen in their hand and put it to their mouth to help them quit. So, any less destructive suggestions?

I already exercise on a pretty regular basis, but that just doesn’t seem to cut it… (hah, no pun intended)
