Our FACTOR B2 was awarded “2022 Knife Of The Year” by many of the top knife reviewers on YouTube including Metal Complex, Jim Skelton, Everyday Minimalist, Nick Shabazz, and more…

…And now we’re back with the new FACTOR B3!...

The new B3 features an impressive list of refinements and enhancements, including:

- FULL TITANIUM SCALES - skeletonized, contoured, and textured! Note that we also offer a full carbon fiber B3 weighing just 2.7 ounces!

- NEW IMPROVED MAGNETIC DETENT - stronger out of the box than the B2 for snappier action

- NEW BLADE OPTIONS - stonewashed M390, polished Damascus, or satin Magnacut - depending on which variant you purchase

- NEW CONFIGUATION OPTION! - order your B3 with a black carbon fiber flip lever (more deployment methods and more fidgety) OR a solid/fixed black carbon fiber backspacer (better ergos)

- NEW POCKET CLIP OPTIONS - black DLC coated titanium OR Timascus (depending on which B3 variant you choose)

- HARDWARE UPGRADE - Torx T8 body screws instead of T6

- HANDLE PROFILE REFINEMENTS - more choil space, and ramped scales for better blade window access

…PLUS, a long list of exciting features carried over
from our Knife Of The Year FACTOR B2, including:

– The M-Lock: The first-ever fully locking magnet-driven lock, for a very tight lock up and ultra smooth action

– The FACTOR B3 Magnetic Detent System (M.D.S.): The FACTOR B3’s smooth action is enhanced by its unique magnetic detent, which also prevents bounce-out or bounce-back when the blade swings closed

Optional Flip Lever Deployment (depending on your configuration choice): The FACTOR B3’s unique “flip lever” deployment mechanism utilizes clever geometry instead of springs to assist in deploying the blade, meaning the blade is not under tension when closed. Actuation via the flip lever is manual instead of automatic in the sense that finger pressure must be applied against the flip lever to deploy the blade

– DOUBLE, shouldered blade stop pins
– Deep carry milled pocket clip
– Ultra slicey blade; extra thin behind the edge
– G10 pivot & lock button inlays
– Stonewashed, damascus, and satin blade finish options (see details of your selected variant above)
– Flip lever slot to house 3mm x 22.5mm sized tritium (light) vials (applies only if you purchase a B3 with flip lever instead of fixed backspacer)
– Ambidextrous flip lever actuation (applies only if you purchase a B3 with flip lever instead of fixed backspacer)
– Chamfered edges throughout handle and blade
– Reversible pocket clip
– Ambidextrous lock: The FACTOR’s M-Lock works well for righties and lefties alike; it’s easy to use from either side
– Captured “D” pivot with ceramic ball bearings
– Auto blade centering
– Large, chamfered finger choil
