Mine are:

My Maxpedition S-type Versipack for every reason I listed in the linked thread, and now the fact that it'll sit lower than a standard pack while I'm riding.

My Morris File Belter. I can't say enough good about Mike's knives. It holds, keeps, and takes an edge well. The high carbon steel throws a ton of sparks for fire building. Its pocket sized if I have to dress "up" and can't have it visible on my belt, which is still a low profile option anyway with its horizontal presentation.

The Surefire E2D. I've handed it to guards at security checkpoints with nary an eyebrow raised. Its bright, light-weight, and capable of knocking an assailant for a loop if you need. Best of all, its billed as a "last ditch impact weapon" by Surefire themselves, so there's no chance of them testifying against you if you use it as such.
