This week we’re spotlighting a product that’s gonna make you want to make like a tree, and get outta here, QTRM5TR’s Biff Tannen flipper. Named for the oafish bully who terrorized two generations of McFly in Back to the Future, this knife is exactly as beefy and stout as you’d expect.

Deployment is reliably smooth thanks to the encased rollers of the patented ORB pivot system. Blade is 3″ long and a robust 4mm thick, made from CPM-154 stainless steel. We’re looking at a Wharncliffe style with a compound grind. Once extended the blade is held in place by a very rugged frame lock with stainless steel insert.

Handle on this model is a tremendously sturdy titanium with that robotic, squared-off look you’ve come to expect from QTRM5TR. Shape feels pretty comfortable to hold, with the various machined elements affording a nice level of grip. The thickness of the handle makes this a super solid carry.

We’ve got this model in three really attractive finishes, a stonewash, Texas Tea black stonewash, or tactical black. I’m a sucker for the Texas Tea, myself. Pocketclip is reversible and allows for a secure tip-up carry.

Overall, the Biff Tannen is a stout, capable folder that’s vastly more useful than a screen door on a battleship. To learn more about this knife, click here. To see our full inventory, visit
