In detail
The Extrema Ratio BF1 CD Black is an everyday folding knife designed for simplicity, functionality, and durability.
The N690 burnished blade has a flat grind and a robust, thick tip.
The handle has distinctive lowered flat sections, also burnished black, allowing easy access to the opening "pins" that remain flush when the knife is closed.
A reversible clip is positioned on the back of the blade, concealing its tang for a discreet carry.
The knife uses a reliable LINER-LOCK system for secure blade locking.
