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.

  1. 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

  3. 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.

    This thing is great. The exact right size. Smooth action opening. Great profile in the KeyBar. Buy with confidence.

  6. The New Benchmark for KeyBar Knife Options 5 Star Review

    Posted by on Nov 17th 2017

    I pre-ordered on November 1 the KB Flipper from San Diego Knives after following the product's progress on Instagram for a few months. The knife finally shipped on November 14 and I received it this afternoon. The knife is well made and functions great as a stand-alone blade and when inserted into a KeyBar. The flipper action is smooth and the blade is top notch. Great construction, great item at a fair price. Of all the blade knife options for the KeyBar, the KB Flipper is in my opinion the best option for those who want to add a little slice to their KB set-up or who want to upgrade to a better and more functional knife.

  7. Great little knife 5 Star Review

    Posted by on Nov 17th 2017

    The design, quality and execution are all that you'd expect from Ferrum Forge and We Knives.

    Good idea & great execution.

  8. Awesome knife. 5 Star Review

    Posted by on Nov 17th 2017

    Deployment is smooth. No blade play. Perfect for the keybar. Now I need a keybar which I will purchase. Bought it because I'm a knife junkie. Even as a stand alone knife it's great. Small but perfect for EDC.
