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.

    Built tough

    Probably the best knife I’ve owned, just bought my second one only because I was afraid they may stop making them! Seriously tough!! I’ve used mine to pry with and even gets used as a screw driver when you in a pinch...and not once was I worried about it breaking or even breaking the tip off!! And that’s saying a lot!!!

    Perfect addition to the Key Bar.

    Published by josh on Aug 2nd 2018

    So i’m new to the Key Bar but not new to knives. very surprised this comes with S35VN. i heard D2 but never saw anything when i purchased. I had to remove a couple keys to keep the Key Bar at a reasonable size to still clip to my pocket. and the deep carry clip i purchased along with the flipper was a major improvement. Fit and finish is perfect. make sure u put washers all around to keep it that way. as much as i love to take apart knives and clean them i don’t think i’ll be doing that with this one. Very happy with my purchase

    Great Knife

    Published by JHB on Jun 5th 2018

    Awesome little knife for every day. Coupled with the bottle opener it functions like a tactical Swiss Army Knife. Came nice and service sharp. Smooth action and solid lockup.

    Awesome little knife!

    I love that this fits into my keybar! It's got smooth action. Nice locking liner. Easy to open easy to close. Nice addition to my EDC. It is very sharp. And I imagine it'll be easy to sharpen once it becomes necessary.
