State and Union OSF Folder, Anodized

(0)
The Old School Folder “OSF” is State & Union’s first take on a frame lock folding knife. The OSF was designed with KA-BAR’s traditional leather stacked fighter in mind, which is why the blade has a fuller or “blood groove”. This knife is a flipper and the pivot is on caged bearings for quick and easy opening. So, if you’re a fan of flippers, this is a knife you need to get your hands on! Equipped with a 3.75” CPM S35VN steel blade, 6Al-4V titanium frame and all 6Al-4V titanium hardware (excluding stop pin, caged bearings, washers, pivot barrel, and lock-bar stabilizer), this knife is built to last a lifetime. The OSF’s pocket clip can also be arranged for tip-up or tip-down carry, so whatever your carry preference may be, we have you covered. If you’re looking for a high-quality folding knife, you can stop your search here!   This OSF features a blue anodized frame and engraving, along with purple anodized hardware.
