Middle row - Pro=Lite Clip Point, AK-47, Scimitar

Other brands I carry in my EDC rotation...a few of them anyways...
Bottom row - Benchmade, AG Russell Folding Spearpoint, Benchmade Phil Boguszewski Spike
Middle row - Syderco Endura, Spyderco Salsa, Custom Karabit (damascus and ivory)

There are others as well and I always have at least a slipjoint in my pocket in addition to whatever "tactical" I am carrying.
