Extrema Ratio BF1 CT BLACK RUVIDO


ER0410000144/RVD

BF1 is an everyday carry folding knife: simple, essential, and functional. The blade is polished, with a flat grind and a thick, durable tip. Characteristic recessed flat areas in the handle – also polished – provide access to the opening pin, which does not protrude from the knife when closed. The reversible clip is positioned on the back of the blade and encloses its end – making it discreet to carry. It uses the reliable LINER-LOCK locking system.

Описанието отговаря, но очаквах по-голям размер. Иначе е ОК.
