The SOG Pentagon fixed blade was originally designed as a back-up knife for law enforcement and military personnel, but the Pentagon series is now popular with outdoor knife enthusiasts as well. The Pentagon offers the instant choice between a serrated or beveled edge for cutting options. The twin thumb notches enable accurate blade orientation and downward control. The checkered handles are flared to provide confident gripping as well as superior feel and balance. The Pentagon comes with a tactical nylon sheath.
I've had this knife for ten years. When walking the dog at night I used to carry it in a paracord shoulder rig with a molded hard plastic sheath (then standard) in case I met up with bad guys. The AUS-8 blade comes quite sharp on both edges. The jimping on the blade haft provides for fine thumb control. The checkered rubbery handle provides a very good grip. Although I believe it's designed as a tactical knife there's no reason you couldn't carry it in the belt sheath for utility use--the double beveled/serrated edges would come in handy on a boat, on the job or in the field, although mainly this I carry it as a tactical knife I hope to never use. The only drawback is the AUS-8 steel, inferior in this price range. I don't use the serrated edge because I'm not good at sharpening serrated edges and AUS-8 dulls quickly The plain edge is easy to bring to razor sharpness on a Sharpmaker.
