Before opening the thread, I was prepared to recommend immodium... <img src="/images/graemlins/laugh.gif" alt="" />

I do have leatherman squirt but have not used it much.. I personally would avoid sharpening it on the other side.. Also, I'm not sure if you want to carry it with your BK10.. if you lose the BK10, you loose both blades. Everyday carry, its on my keychain. If I'm hiking and such, its on my lanyard with my whisle.
