Kershaw Mini Biner

Basic but functional, this is a convenient little knife — but it is dull out of the box, so you'll need to sharpen it

This is a nice little knife that's really handy. The built-in carabiner makes it easy to clip on anywhere anytime, and the stiff action of the biner's gate (which has held up well over time) keeps it from coming loose accidentally.

The blade also has pretty stiff action which ensures that it won't open accidentally or shut without some decent pressure — a good thing since this is a non-locking blade. I keep mine on my keychain and it proves useful for countless little cutting jobs. 

My only complaint is that the blade was surprisingly dull out of the box.  It was easy enough to put a decent edge on it, but you will want to sharpen this one.
