The Extrema Ratio BF2 is a full size folder and is a favorite of first responders. The handle is ergonomically constructed to fit your hand for a solid, secure, and comfortable grip.

The BF2 is a robust, dependable knife that provides you with an excellent EDC. Since some jurisdictions restrict blade length to four inches or less, this shorter blade will be legal.

It is rust resistant - plus it has an exceptionally sharp edge. The BF2 has an easy-to-use liner lock combined with a manually activated locking mechanism that should be used for additional secure locking.

The clip is reversible side to side. This bridge clip allows a deep pocket, discreet carry.

You can see, and feel, the quality when you handle the BF2 - this is a superior pocket knife that slips into your pocket for a great EDC. Durable and dependable.
