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.
