The BF1 is a folding bag for everyday use, simple, essential and functional. The blade, exclusively burnished, has a flat grind and the tip is particularly thick and resistant. The grip, also burnished, has characteristic lowered surfaces to engage the opening "pins" without them protruding from the profile of the closed knife. The reversible clip is positioned behind the blade and embraces the tang of the knife so as to hide it completely if inserted in your pocket. The blade locking mechanism is the proven LINER-LOCK.
