Boker Plus - Urban Trapper Jigged Titanium knife by Brad Zinker - 01BO476 - coltello chiudibile
Brad Zinker riesce sempre a scoprire nuove sfaccettature del popolare Boker Plus Urban Trapper. In qualità di maestro coltellinaio, il designer di coltelli statunitense sa meglio di chiunque altro come reinventare i design esistenti di coltello gentleman con combinazioni intelligenti di materiali.
Il Boker Plus Urban Trapper Jigged Titanium è dotato di una lama VG-10 con superficie rettificata e cuscinetti a sfera con una finitura sottile, che si apre con un flipper ed è fissata da un robusto linerlock.
Un accento moderno è dato dall'impugnatura in titanio, che rende omaggio agli innumerevoli classici con guancette in osso jigged. Questo non solo posiziona visivamente il coltello in primo piano, ma migliora anche in modo significativo la sensazione del coltellino tascabile.
La clip per il trasporto profondo in acciaio inossidabile consente il trasporto ribaltabile (r) ed è rifinita con una finitura stonewash.

Notes: Design by Brad Zinker
While we've seen plenty of Boker products over the years, resourceful knife makers continue to find ways to surprise us. For example, Brad Zinker from Florida with his Urban Trapper, one of the thinnest profile titanium framelocks we've ever experienced. With just 8mm grip thickness (without clip), the term "slim" only inadequately describes the Urban Trapper for its usable size.The large holes and titanium transform the Urban Trapper into a real featherweight of just 48 g that can be carried extremely comfortably both in a suit pocket and in light summer trousers. Considering the overall minimalist design of the knife, the size of the flipper is equally reserved.
When used, it still impresses with its outstanding functionality and reliably opens the blade on VG-10 ball bearings. The blade shape of this classic trapper pocket knife, widely distributed in the United States and worn for many years by Brad Zinker, was the inspiration for this unusual piece.
