FACTORY 2ND’S are now available! While supplies last.

Factory 2nd blades are just as functionally fit and come with the same KRUDO Knives warranty that you know & trust, but have some cosmetic difference(s).

Possible reasons a knife is considered a Factory 2nd would be smudge, scratch, color variance, chatter mark, some cosmetic inconsistency. 

You get a fully functional KRUDO Knife at a fraction of the cost. There will, however, be some unique, cosmetic difference that makes this item a 2nd.

No coupons or added discounts will apply to any Factory 2nd item.

Welcome to a world of controlled chaos! If you are struggling to manage the unmanageable then you need to add a little DISCIPLINE to your life. The DISCIPLINE folder, a Louis KRUDO design, created with a sleek new look, coupled with the  KRUDO Thumb Wedge for pocket deployment and surprisingly fast manual deployment makes owning it a necessary pleasure.   With a solid, tactile feel and optimized as a lightweight EDC, the gentle curves represent a rising sun, complemented by the added G10 in a sun ray pattern. Boasting ceramic ball bearings, the reduced friction creates super fast blade deployment, critical to a situation where DISCIPLINE is needed.  Putting all this together you get a thick blade with a sculpted frame, providing out of the pocket lightning fast opening, in a folder weighing only 7.1 oz. Challenge the status quo and add the DISCIPLINE Folder to your collection.

The KRUDO Standard, Factory 2nds


  1. Derrick

    The Disciplne is an amazing tool and rides in my pocket every other day, it alternates with a Krudo DAO.
    The build quality is exceptional. It is big and heavy and that is perfect when your adrenaline is up and your fine motor skills are down. You can always get your mitt on this tool when you need it.
    I’m calling it a tool and not a knife because cutting is just one of its possible uses.
    The thumb flipper, finger flipper, and thumb wheel do an excellent job rapidly deploying the blade. But in the closed position they protrude far enough to be used very well as compliance and control tools.

  2. PD

    The Discipline is an AMAZING BLADE. It has already saved me a couple times. This blade is devastating and strong and can do whatever job you hand to it. Get you one or two Krudo Blades you won’t be sorry.
