Overview
Our original FACTOR was awarded “Knife Of The Year” by many top knife reviewers including Metal Complex, Jim Skelton, Everyday Minimalist, Nick Shabazz, and more…
…And now we’re back - and better-than-ever - with the all-new FACTOR B4!...
The FACTOR B4 is the very latest (standard size) FACTOR iteration with numerous significant advancements over previous versions, including:
- NEW-IMPROVED MAGNETIC DETENT SYSTEM - our strongest and most adjustable (standard size) FACTOR magnetic detent system to date (with two detent magnets instead of one), for extra snappy deployment action and easy customization!
- NEW-IMPROVED TITANIUM FLIP LEVER - enhanced lever geometry contributes to the extra snappy & fidgety action of the new B4 (the B4 is still 100% manual, but feels almost like an automatic)!
- NEW CONFIGURATION OPTIONS - 12 exciting variants to choose from (our most ever), including new black DLC blade options, new timascus accent options, and more!
