The Story:
The idea sparked when I was using my KeyBar at work. I’ve always had my favorite knife, a Ferrum Forge Stinger, in one pocket and the KeyBar in the other. But one day I forgot my knife and I was trying to cut a zip tie with a key (we’ve all been there). I went that afternoon to see Elliot at FFKW and tell him about my idea to add a real knife to my KeyBar. -Andy (Nalpak, Inc.)


Will the KB Flipper work in any KeyBar? Yes, it will fit and work in any KeyBar with any keys or accessories.

Can you use the KB Flipper by itself? Yes, it is a stand-alone locking knife.

Will you be making any other blade shapes. Not at this time but we may in the future.

Can I take the KB Flipper apart? We suggest you don't do that as the bearings are loose and will fall out.

    Fits perfectly into the KeyBar and opens quick and smooth. One of the better knife inserts I’ve purchased for a KeyBar. Great product and very well made!

    I'm glad I stumbled across this flipper, I have been looking for a knife attachment for my Chavez edition keybar for over a year and all of the ones available have been out of stock or just not available anymore. Well good things come to those who wait, this flipper blows all the other knife attachments away, razor sharp premium steel with a flawless fit and finish at a great price, perfect size and weight for the keybar.

    I’ve had my flipper for a few days now and I love it! It’s smooth and as sharp as you could need. The best accessory for your keybar! Or even used as a stand-alone knife.

    Love the flipper for key bar. The only thing is I would love a titanium version so I can anodize it. That would make it 6 out of 5 lol

  7. Ferrum Forge does it again 5 Star Review

    Posted by on Dec 11th 2017

    Ferrum forge makes great knives. So when I saw an add for the kb flipper I thought that looks cool..but is it practical?
    And I answer with a resounding yes!! Besides fitting perfectly flush in my keybar, it is incredibly easy to hit the frame lock to release the blade, which by the way is made of s35vn and came very sharp. At first it was all about second kind of cool where it just looks awesome in my keybar, but I use it daily..packages, tape all kinds of tasks.
    I am very impressed with the fit and function of this tool. Ferrum forge has gotten in my pants, now they own a spot on my keybar..

    Super cool piece of EDC whether in keybar or on it's own

  9. Great addition to my Keybar 5 Star Review

    Posted by on Nov 24th 2017

    Preordered this item and received it after the production shipped. It appears to be a good quality knife and fits my KeyBar perfectly. Action is smooth and the lock is easy to work. The blade centers in the liner which indicates attention to detail and quality of construction. The edge was adequate out of the box but after a little time on my EdgePro it got even better. Doesn't interfere with deploying the keys in the KeyBar. If you carry a KeyBar I would definitely recommend the KBFlipper Only way I would be happier with the item is if it was Made In USA.

    I’ve been waiting for a knife to come out for the keybar for two years. The quality of the kB flipper does not disappoint. Totally worth it.
